Great explanation of where infrared falls on the visible spectrum. Your demonstration o the door shows it's important to remember this is not x-ray vision. In the technical side, I can see customers using this in a hunting application get confused when their rabbit or deer disappears behind thick brush or a large tree trunk.
How does a fire extiguisher with powder work with IR? Can you effectivly jam IR, visible light and thermal cameras with laser light in the right spectrums?
Thank you Roswell Flight Test Crew. Our company uses the FLIR Tau2 imager except we rotate it continuously in our camera so that we are able to continuously have a 360 degree thermal image panorama for wide area intrusion detection. Thermal Radar is our product. Thank you for the great explanation. I love sharing your findings with my customers to better inform them about thermal imaging.
Is there a way to detect heat and cold that is in the open air of a room using thermal imaging? I know you can see the heat on solid objects but what could you use to detect a mass of air that is colder or hotter than the surrounding air inside a room? Hope you keep up the cool work! Thanks
Yes, but it's not nearly as visible. When he does the dry ice test and you see the foggy shimmer its actually the cold air being picked up by the thermal. Granted if the temperature is not huge it's very difficult to see, but I have seen farts, car exhaust, dryer vents, ect. It kinda looks like how you see with the naked eye thermal heat waves in the summer.
What a great informative video thanks can I use this thermal imaging to see where these squirrels are going in and out of the house, we've done our best to close up everything with metal over the holes would it be feasible to use a Flir, FLIR brand adapter to a cell phone to film this, and then run it real fast and watch for the blazing hot squirrels in the movie, then stop the film and discern where they're getting in?
ntme9 ...it isn’t a lens in the sense you would think of a camera. It is the IR sensor which looks like a lens but is actually “seeing “ minute temperature differences in the IR spectrum.
So metal hides heat signatures? What types of metal? Can a suit be implemented if made of metal sheeting . Or at min, break up the signature? Thanks.. great video sir.
@@N.E.U.R.O thanks man. And I concur. I got a reflective tent and made it into a hoody type shirt with mesh camo over top and you can't see my shape, least on the type I have.
Is there a preferred color for tricking thermals into thinking it’s a temperature of a certain kind? ie. certain shades of grey or black/white etc or even transparent and coated materials of that. ie. silver but mixed with a specific color palette for better effect or thermal distribution from sun/body heat? sorry for the rambling question.
I am searching for my kitty in and around the I-40 rest area called Gray County Safety rest area in Texas. She was lost there on tge night of Sunday, August 24, 2022, as she ran through the rain in fear. Could I use IRT to check for her in hidden places and through heavy grass and brush? What about in the pipes that go under the freeway? Does it take much training to make good use of this tool?
Pulsar is much better than flir, so if you want to buy a thermal unit look at the microblometer resolution as the screen itself can be 1080+ but if the microblometer is 120 you will only get a 120 resolution. As the microblometer is in essence what detects the thermal radiation. If you really want the best in a handheld go with trijicon as they have the highest thermal resolution (you will pay very dearly for it) pulsar comes in second at 720p and flir is half that. Alternatively if your rich you could buy a cooled unit (like the police choppers use) in that case flir is the best but your talking a few hundred thousand dollars at that point.
In most places, the night time temperature is much cooler than a human body so all you have to do is wait. The insane heat our bodies produce will eventually bleed through or the person dies of heat stroke. Either way you win.
When creep next door, monitoring me in bathroom by using some thermo device, can survivor sheet block that ? If not, please let me know what can I use to block this kind of stalking.
Great video, thanks for sharing. I'm trying to find a sensor that can see past thick hair. Might you know if radio waves, thermal, sonic, or something else will do the trick? Thanks very much.
You know how in very hot conditions, the heat coming off the ground can make wavy patterns in the air, a type of mirage. Does that kind of effect happen in thermal imaging as well?
I want to know if you can catch CO2 with an IR camera but not, say, NO2, because CO2 is a greenhouse gas (thus can absorb and reemit IR) but NO2 isn't? And what about hot CO2 and NO2? Do they look different at the same temperature because of the greenhouse gas property?
I was wondering if you know if old tv screens, projection TV's, the big Sheetz of plastic that are inside the images are projected on, would that work to evade this?
Frankly a space blanket can easily block thermal, basically anything that stops the thermal radiation from passing. The issue (if your trying to hide) is that the space blanket will look super out of place itself, granted you wouldn't know there's somebody behind it as long as it's not touching you or the heat source, but it would reflect the surroundings acting like a mirror, moreover if you're outside it and it's angled up it would show up as very cold (just like car windshields do) as it would reflect the coldness of space. So if you were hiding and I looked through the thermal at you I would see an extremely dark square, my own reflection, or whatever is in front of the blanket, glass, ect.
So those reflective insulating material we see on the inside of jackets, if we turned that inside out, theoretically we wouldn't be able to see the jacket because it's reflective?
Yes and no depends on the inferred spectrum, near inferred (what you are talking about) is so red you almost or if further along can't see it with the naked eye, this is the same technology your TV remote uses (hold your remote up to your camera on your phone for example). Anyway thermal inferred is generally much further along on that spectrum you can see it if it's hot enough (think catalytic heaters for example) but generally it can only be detected via a thermal imaging unit as a regular camera can only see the near inferred spectrum as such near inferred doesn't show up on thermal either.
Yes there is thermal paint, it's designed to reflect space / cold and is aimed at an upward angle or on roofs. It doesn't have to be angled as such but basically acts as a mirror and will reflect the thermal inferred radiation, for example if you aimed it at trees then looked at it it would reflect the trees.
3:43 i hope you see the message. Don't? it says; wanted todo a live demonstration for you. but everyone else was afraid that i'd burn down the studio in the process...
im not certain about details. But often firefighters are not stumbling through fog, but rather through smoke. These are 2 different physical things with different properties
The dry ice they used emits cold CO2 wich is visible as a cold fog, but normal H2O fog is very hard to see unless it has a big temperature difference compared to the background. And when you don’t see it, you’ll see trough it.
when I was a kid, I tried to glow a matches with optical lens trough a window glass. But it can't. But when the window was open, it works. I understood something was going wrong, but I was to young to understand existence of infrared light.
You can see the studs in the wall but that's about it, it can only see those as they sit against the outside wall and absorb / disapate heat slower. For example if you set up a tent and someone was inside you probably wouldn't notice them unless they were putting out a lot of heat (enough to heat the walls).
No, but it likely will show whether there is any internal heat from the vehicle. It will also show heat around the engine, tailpipe, and even the tires due to friction from moving on roadways.
Ron Zorro a German company is making a set of camies just for that. the US army uses blends and coatings in bdus back in the 90s. a cheap way uses a couple layers of space blanket with a inch or 2 of light heat dispersing insulation
There would be no difference, as the thermal wouldn't determine different colors so white black ect would look the same, now there's one thing that would change this being exposed to sunlight. Obviously the different colors would absorb different amounts of heat from the sun and in turn would give off different temperatures accordingly. If using white or black hot (my unit only has those options) it would show up with almost all no difference for the white tape and would show up as hotter for the black tape. Moreover different types would react differently as the material would absorb the temperature differently.
That's why I didn't go with flir, mine sees the different temp of water in a silver can. Anyway I didn't come here to bash flir, I wanted to mention that you never mentioned my favorite part about thermal imaging... You can see through a tarp or plastic garbage bag almost unadulteratedly, theres a slight shimmer of the bag giving off it's thermal radiation but beyond that you can see through it pretty well, the closer and hotter the object on the other side the clearer the image through it, (this also works with very thin clothing). The downside is if your trying to walk you could easily not notice the plastic sheeting. Also a fun fact you can see hot/cold gasses like your dry ice test where you see the slight whisps of the cool air so you'll know who let it rip if you happen to be watching with the thermal. Last but not least despite not seeing through glass (it can't because as you mentioned it sees the surface temperature) if you were to touch the glass on the side away from the thermal for long enough your handprint would eventually bleed through and could be detected, for those who don't understand it's because of heat transfer that warms up the glas in that spot essentially warming it enough that the other side gets warm enough to detect. Beyond that the points you talked about are spot on just figured I would add some info that I had wondered about for many years (until I dropped the multiple grand it cost to purchase one and find out). If this comment gets idk 20 likes I will post a video showing more fun things utilizing a 720p thermal microblometer (the thermal sensing chip). Oh and one last fun fact, the original thermal imaging systems required liquid nitrogen to operate and were upwards of $80,000.00 that is until the microblometer was invented as the chip itself is in a vacuum allowing it to detect the thermal inferred radiation / aka heat.
It would be nice if you guys did a review on the Sparkfun Lepton Flir break out board diy thermal imager. Low pixels at distance may be cool to compare.
+Hoverbot1TV We've been talking to FLIR for a while about flying a Lepton imager, to see whether or not it would be safe and/or practical to use one for FPV, owing to the extremely low resolution. It's something that we're looking at doing at some point in the future, although they (understandably) want to be cautious about suggesting, even by implication, that a piece of their technology be utilized for a task that it isn't well suited for -- especially something like controlling a drone, where there are legitimate safety concerns. However, it is definitely something that is being discussed. Stay tuned.
They are friking AWESOME!!!! I absolutely love mine (I also love going on night hikes). I will forwarn you these are definitely not cheap, but for around $2000.00 you can get a pretty darn good one just do your homework and ignore screen resolution (it will be like 1080 screen resolution) but you want the microblometer resolution instead (that's what detects the thermal radiation) your image will only be as good as that resolution. Unfortunately they like to trick you with high screen resolution despite it making no difference as long as it's at or slightly above the microblometer resolution. I/e flir has a 1080p screen but only gets 320 for the microblometer. Moreover check out pulsar there way less money for way better imiging.
can you explain how a mirror would react to thermal imaging will it show a thermal image in reflection will it be just like the containers nothing or like the glass nothing
A mirror will react just like it does normally, except it will be a thermal reflection instead of regular light. When I first got my thermal unit I scared the H*** our of myself when I was looking around my friends house and didn't know he had a wall mirror, I turned to face it in a pitch black room and to my surprise there was this person standing right were I was. Obviously it was just my reflection but this was before I knew about far inferred light radiation.
Great question! The answer is: the lens isn't made of glass -- it's made of precision-ground Germanium (Atomic number 32, "Ge" on the periodic table). It was discovered in 1885 in a silver mine in Germany (no surprise there). The fact that Germanium, instead of glass, has to be used to produce the lenses for thermal cameras is one of the many reasons they are so expensive.
Fog does obstruct thermal radiation. It's just that fog blocks visible light better than thermal radiation. The video shows the thermal camera sees though the fog much better than visible light camera. It's possible to detect CO2 with a thermal camera but the effect is much much weaker than the effect from fog. It would have been interesting to see if the thermal camera could have detected CO2. Usually a special filter is used when detecting CO2 since it's much harder to detect.
Fog can affect thermal, if the fog is thick enough it will limit your range and details of the object you are looking through the fog at as much like a blanket it does absorb some of the heat. The dry ice was more so in the fact that it's giving off cold. I am a hunter and I have a thermal.
Lucidity!!! Shame no one let you use your props for the test!!! I was really looking forward to check how they work! lol PS: thanks so much for the video love the demonstrations! Hope to see you at flitefest 2016! Gladly will be able to be there this year! Ed
Can not understand: If a metal can reflects the thermal emission back inside, and the thermal camera can not see any difference, why then the outer surfaces of the cans are HOT and COLD when touching them? If its surface is hot then it should illuminate like the phisical Black Body. So, there is some gap in my understanding. The tape attached to the cans - illuminates IR, but the hot metall surface does not illuminates IR - why? Incandescent bulb when red-hot illuminates in visible red even yellow color and we see it bare eyes, but why the thermal camers can not see InfraRed when it is warm, not hot??? If we heat up the can to Red-hot it will be red illuminating, isn't it?
@@dennishaines5717 tx for the info..Neighbour below-bizarre habits-thermal imaging me and infra red heat to extreme !!!!!!, tried aluminum slab/black plastic bag/mirror--nothing helps!
no, since you would just see the "water temperature" in front of the camera. If someone pees directly in front of you, then you could see some swirls, but it has to be very close to your point o detection (the camera)

Obviously it was just my reflection but this was before I knew about far inferred light radiation.
Make a video with a Flir camera "underwater"! Like in a Coral reef, where one may see Fish swim by or in space, ..
Turn off your screen and then you see a video made with a thermal cam under water.
don´t understand, what you mean by that. Are you being sarcastig?
Yes.. sorry. Water is not transparent to these wavelengths therefore it won't work to record a video under water.
How I can make a Poncho Man ... A coat to wear AND aboid the thermal image ???
Can thermal see through plexiglass?
You should have shown the black nylon trick as well.
Why dosnt the lence of the camera block infrared light
Great question! The answer is: the lens isn't made of glass -- it's made of precision-ground Germanium (Atomic number 32, "Ge" on the periodic table). It was discovered in 1885 in a silver mine in Germany (no surprise there). The fact that Germanium, instead of glass, has to be used to produce the lenses for thermal cameras is one of the many reasons they are so expensive.
Because lenses for thermal cameras are made from Germanium.
What about fiber glass?
Fog does NOT obstruct thermal but Co2 does (dry ice is Co2)
Many hunters use it because of they can see everything in the fog
Fog does obstruct thermal radiation. It's just that fog blocks visible light better than thermal radiation. The video shows the thermal camera sees though the fog much better than visible light camera.
It's possible to detect CO2 with a thermal camera but the effect is much much weaker than the effect from fog.
It would have been interesting to see if the thermal camera could have detected CO2. Usually a special filter is used when detecting CO2 since it's much harder to detect.
Fog can affect thermal, if the fog is thick enough it will limit your range and details of the object you are looking through the fog at as much like a blanket it does absorb some of the heat. The dry ice was more so in the fact that it's giving off cold. I am a hunter and I have a thermal.
how do objects(wood, paper, plastic) look like inside of juice bottle using thermal camera
I'm wondering if the IR camera lenses are still made of glass!!!
They never were. Germanium, silicon, zinc selenide, etc, are typical materials.
What about black smook like tires one🤔🤔
Does your head always wobble when you talk?
Lucidity!!! Shame no one let you use your props for the test!!! I was really looking forward to check how they work! lol
PS: thanks so much for the video love the demonstrations! Hope to see you at flitefest 2016! Gladly will be able to be there this year!

+rifted Tell me about it!
so you can basically use glass to make a tank invisible in the night ?
How about mylar blankets?
What is NUC
KU band and other forms of back scatter can see through most everything, mix with multi spectral you can render an image like that seen in the movies.
+The Tinfoil Tricorn Wow! Can you post a link? I'd love to see it in action and understand how it works!
***** that should help point you in the right direction
Can not understand: If a metal can reflects the thermal emission back inside, and the thermal camera can not see any difference, why then the outer surfaces of the cans are HOT and COLD when touching them?
If its surface is hot then it should illuminate like the phisical Black Body. So, there is some gap in my understanding.
The tape attached to the cans - illuminates IR, but the hot metall surface does not illuminates IR - why?
Incandescent bulb when red-hot illuminates in visible red even yellow color and we see it bare eyes, but why the thermal camers can not see InfraRed when it is warm, not hot???
If we heat up the can to Red-hot it will be red illuminating, isn't it?
How do I make one from scratch at home that works?
How X RAY night vision scope buildings or forest. ?
Terahertz camera's could see thought thin walls and some materials.
I thought glass is transparent for any wavelength between 300 to 4000 nm?
Depending on type, I believe glass cuts off around 2-2.5µm.
Can night vision camera see through blanket
Please please answer me
no
Yes it can but not if you use mylar survival blanket
@@dennishaines5717 where does one buy the mylar blanket ? tx
@@sherryhansen5228 Walmart should have. Any outdoor stores will have. It's just a survival blanket
@@dennishaines5717 tx for the info..Neighbour below-bizarre habits-thermal imaging me and infra red heat to extreme !!!!!!, tried aluminum slab/black plastic bag/mirror--nothing helps!
Hi! Can anyone tell me if normal glass absorbs or reflects light? He said ‘blocked’, that’s not good enough
Reflects.
Glass transmits light (mostly) and reflects a little, ie, as in a window. It blocks mid- and long-wave IR, which is how greenhouses work.
Use for during operation vernacular night vision scope X RAY building or forest.
What is it that makes thermal imaging devices so expensive
one big cost is the germanium objective lens in the front. I just bought a bigger one for my pulsar, and it was $900
Can these thermal imaging be used under water
no, since you would just see the "water temperature" in front of the camera. If someone pees directly in front of you, then you could see some swirls, but it has to be very close to your point o detection (the camera)
dude, next video on our thermal camouflage
what does see through fog then?
Hello. Hey i need a scope to catch avocados thief’s at night. What do you think would be better: a night scope or a thermal scope?
Its important to tell you that they hide between the trees!!!
@@manueljosegana2237what's the difference?
if a thermal camera cant see through glass, why can i see through the glass lens?
The material used for thermal lenses is made of Germanium
@@UV-NIR-Thermal WOW! thank you for taking the time to reply. I've learnt so much about fiber optic and germanium just by double checking your comment. You game me a ton of knowledge just by replying. Thank you!
@@Gex121 No problem, happy learning
