Thermal imaging and its neighbours are fascinating. I worked many years for FLIR as a service engineer before I retired but I'm still nerdy about it lol
@@taiwanluthiers I had a FLIR One for my iphone a few years back, it worked very well, was able to examine several things and find cold spots where there was no insulation on my apartment, plus a few small water leaks, you probably can do better with a hand-held FLIR camera like the FLIR C5 instead, the FLIR One attachment was a pain to use on the iphone because I needed to remove the phone case for it to connect properly, and lighting extensions were too wobbly. Then one day the FLIR attachment just died, wouldn't turn on or charge its battery, dead, zero, nada.
I had a phone with a FLIR camera and I loved it. Mostly for fun, but occasionally very practical. I still miss it sometimes, I think my next phone is going to have it again.
We do not tint the light green, it is the property of the scintillator light (or rather was, since nowadays different scintillators are used). Also the human eye is actually more sensitive to light at about 507 nm when in dark (using rod cells instead of cone cells). Yes, we see the color green the most, but that is for colorful image. With monochrome image, it is more useful to use the said 507 nm light. Great video though, love it!
@DrakeDaraitis no, color corrected means 'achromatic', or no difference in optical behaviour as a function of light color. If the optical system only uses one wavelength of light then the design and manufacture can be simpler.
Our company worked with IsquaredTs early on. It is not the sensitivity which is the problem, it is the "dynamic range" of and amplifying devices. When used in practice, the "bloooooming" effect lasted so long, that the recovery interval became the limiting factor. In actual fire fights they became unusable, and it was easier to just look out with ordinary eyeballs. The attack and recovery problem still exists today. Modern cellphones have much better speeds, but only at the expense of sensitivity. This is a fundamental physics issue, and cannot be undone.
Great point man! I believe that modern IITs (image intensifier tubes) have a cool solution to this, the autogating power supply. Im not really technically inclined to elaborate on how, its like the power supply "detects" heavy light influx, and pulsates power to the tube, reducing incoming light and singificantly helping not to flood the user and bloom the tube.
@@ZaGe_Jet Well explained regarding the autogating. Autogating technology is super powerful and paid dividends in how L3 tackled it in their analog tubes.
The microchannel plates developed for image intensifiers are now used in a variety of scientific instruments to intensify single electrons when used to measure electrons produced when material is irradiated with Xrays. They are often backed with 2 dimensional delay line detectors rather than a phodphor scintillator. With this you can count single electron events and then also get a position of where the event happened. Coupled with an electrostatic energy analyser you can often measure the kinetic energy of the electron and the angle from which it was emitted from the sample. This is the case for angle resolved photelectron spectroscopy ARPES. This is one of the foremost techniques for measuring the band structure of materials and is pretty much the only way of checking the quantim mechanical calculations used to model the electronic characteristics of new materials for new semiconductors.
Great video overall, just some things to note: 14:57 the battery pack for the for the PSQ-20 goes on the back of the helmet, not the hip - you can see it in the image. This helps to provide counterweight on the helmet among other things. Analog intensifier technology is likely not going to go away anytime soon due to how energy efficient it is - as an example, a PVS-14 running off a single AA battery can run for 40-50 hours, something that current digital night vision technology can’t match. Very useful for extended field operations etc
With all the food analogy, really missed the opportunity to mention cut rock candy, which is very similar to the 2 draw process. An image is built up using sausages of colored candy on quite a large scale, and then stretched repeatedly, forming a rod of sugar made up of all the colored bits, which when cut has a tiny, detailed colorful pattern or picture inside it.
The drawing process is also reminiscent of how multifilament low temperature superconductor wires are made, which have many very fine niobium titanium filaments in a copper matrix for stability. Starts off with a large block with cylinders of NbTi in it, which is progressively drawn down to the size of a wire. Amazing it works as well as it does.
My father ran the first field evaluation of the starlight scope for helicopter use in the U.S. army in the 60’s. He was an first Lt and an engineer. He also performed the first motion picture Kerlian theory photography using it.
I have a gen-1 NV monocular, and despite being "old technology", it really does an amazing job making objects visible in low light. It was a blast using it for night-time paintball games.
I have a Philo Farnsworth gen zero tube. I used an ebay tazer exciter to power it. I used pieces of stainless exhaust welded together for a handle and a holder for it. I had to use 700meg ohms of resistance to drop it from 15,000 to 900 volts for the grids. And I had to buy lenses. It works good enough to see around with an IR light.
Anothering to mention is white phosphor screen have taken over green phosphor ones. It doesn’t seem like the theoretical ability to distinguish shades of green actually translates to actual performance, most prefer the bluish greyscale of white phosphor and it doesn’t cause eye strain as much
Not true. The most you can argue would be them being equivalent in performance, or slightly worse than GP at the highest end. It's just preference, I've never had (or anyone else I've spoken to) discomfort from a night vision device just because of the phosphor colour, lens quality or improper use are far more likely.
The blue white tint of white phos is actually better for the rods in your eyes which specialize in light and peripheral perception. While the green tint is better for the cones in your eyes, which help with color preception. So white phos actually allows you to "see" more in the same conditions. It's the same as when you notice stars or glow in the dark stuff in the corner of your vision, but when you look directly at them they're hard to spot.
When digital sensors get coupled with tube output screens, usually green phosphor is used. Even though the digital image is B/W in the end anyway, GP delivers more information. Photonis works this way
As somebody who subscribes to quite a few "tactical" channels, I saw a pair of nods in the thumbnail and just kept scrolling past... but I immediately did a double take and clicked on the video when I saw your thumbnail title design and realized it was made by your channel xD
I learned a lot about light intensifiers and thermals from some Estonian soldiers that keep showing up on my YT Shorts (maybe because I watch it every time :)
@@TheWizardGamezI shoot and hike under nods a good amount and I definitely prefer white phosphor. The black and white color scale is way better for my eyes over longer periods. The green definitely has the nostalgia factor covered though.
Veritasium did a really interesting video on the latest generation of image intensifiers in the US, and it's genuinely incredible that these are basically still running like CRTs in the 2020s.
A.. Family member.. was an optical engineer and helped develop much of this technology alongside the creator of this tech. I remember when they started blending IR and NV.
Would love to see a video with some detail on quantum computers. Everything I've seen talks about how qubits have superpostion but never explain how you make useful calculations from that.
The image at 2:59 is a canal defense light version of the M3 Lee/Grant medium tank. To my knowledge, no night-vision devices were integrated onto these tanks. I have heard about German efforts to mount NVDs to Panther tanks, but I don't know a thing about equivalent Allied efforts or if any existed.
12:32 This caption contains an error. The goggles shown are the PG1MS, a first generation binocular system, nothing like a gen 3 or "higher" system. The AN/PVS6 is a large handheld observation device. and shares no similarity. It's very likely the writer on that source post misidentified them as the AN/AVS-6, a binocular device that can be equipped with 3rd generation intensifiers
In my military service days some 30 years ago I went and froze my thumb to then almost current pretty heavy handheld light amplifier. Getting as a watchman not only the view of the surrounding territory but also the starry sky was a thrill. I can tell all a relatively bad frostbite is more painful than than a burn. A couple of weeks of skin peeling, danger of exposed subcutaneous tissue getting inflamed, but the pure wonder of the experience was something to write home about.
Never thought I’d see the Asianometry cover NV. Frankly the NV hobby really lacks video creators who understand the tech to the level this channel usually has. Great video
Another excellent video as always. Many thanks for using the modern approved subunit "micrometre" (with only one minor slipup back into "micron"). Looking forward eagerly to your next adventure into technology. 😊
Asianometry, have you ever heard of DKL heartbeat detectors? They were featured in the novel Rainbow Six by Tom Clancy, and probably inspired the heartbeat detectors in Call of Duty Modern Warfare 2. I've tried to look them up, but the scant information I've been able to find makes it seem like they were snake oil and never actually worked.
Mom always told me not to go YouTubing before eating, appears she was spot on. In the mid 80’s I got to pop rounds through an M-14 equipped with a late Vietnam era AN/PVS-2. I had always viewed it (lol, pun) as primitive and not terribly useful, not entirely true. While it wasn’t what we consider good now, I was really amazed at how well it worked without IR help. I certainly wouldn’t want it as my primary today, but I can see how it would still be useful, even now, no wonder that era are still available used.
I just bought my first set of night vision and I was so curious how it works. Thank you for simplifying this information. Night vision is so expensive because of the "manufacturing process" so now I get a better understanding of the creation of my $10,000 toy
How does burning thermite at night affect night vision? I am thinking about the thermite drones we have seen lately in Ukraine. Could thermite burning be a way to cover your movement/retreat from enemy nightvision?
Huge part of the perceived overwhelming prowess in combat of US troops and SOF in the last few wars was due to the total overmatch in sensor technology. If the enemy had any NV or thermals they rarely had proper training for them or they were poorly maintained and in too few numbers to matter. This factor too will be radically different if US goes to war against peer or near peer enemy in the future.
The modern systems, both thermal and starlight, are amazing - both quality and super low power consumption. And that was just what we used 10 years ago in theater. Only poor performance in very low night light, when we switched to thermal. They are a total game changer on operations, prob saved a few of my mates several times over. Great presentation - a rightly prized and protected form of tech that should be guarded very, very carefully. Greetings from Spain.
Legacy Collectibles UA-cam channel has a wwii infrared scope that they got working! They have a video on it, it’s really neat. Thanks for the video btw!

Their products are used in the semiconductor industry in many different crucial steps. Could you make a video about the company? Thx!
Regarding the closing remarks: I'm thinking even when evolving to digital technology it probably still makes sense to intensify first using conventional technology before feeding the image into an image sensor.
I have a microchannel system ! It's a Tektronix 2467, 4×350MHz analog 'scope, a delight to use but there is the warning to not push the sensitivity/light too high / too long or it could get damaged...
Fun fact the best goggles are now white phosphor and give a white image. They are much easier to judge distance and size with but are a little harder in the eyes. I use them regularly
I want to thank Dan O. too for suggesting this topic too…. damn fine job Dan! What’s next? I vote for Claymore mines or, idk, nuclear triggers!?! Yeah! Lolol
think about how cool it would be to strap on some goggles and see WiFi deadspots in your house or be able to determine where interference is being generated...
