thank you for documenting real life magic :)
Can you guys collab? please? pretty please?
Beautiful demonstration, I think this is probably the most elegant depiction of light's wave behavior I've ever seen.
I'm sorry?! This may be the most stunningly beautiful representation of light I have ever seen! Thank you so much!
Visualizing the wavefronts of the diffraction/interference pattern as they "travel" through space by changing the image plane was a pretty mindblowing thing. I never figured to think of it that way! And in this case, where there's a very pattern-y interference pattern at different distances, likening it to water ripples as you change focus, showing how the wavefront moves from the diffraction grating to the lens.
Thinking about light as having their wave interactions seemed super difficult to wrap my head around, but this "view" of it makes it so much clearer! Your videos are awesome!!
what a gem of a channel. the youtube algorithm has finally decided to recommend it to me.
Definitely the coolest, most interesting, and most optical thing I've seen on UA-cam this year! Thanks again for an excellent video and for your continued presence here.
"this year"? :)) I'd be very interested in your list of such things over the past 10 years
Go to Slow Mo Guys where they take video of light acting like a little Wiggly wave
At something like 3 peco
seconds
3 trillion frames per second
The Slow Mo Guys aren't actually doing it but it's cool either way
Just found this channel! You're amazing, please keep it up, we need more of this highly technical stuff in youtube!!
This might be the greatest physics video on UA-cam. And that says a lot...
i want to sleep. but i went the rabbit hole of your videos and I can't stop. fascinating works
One of the most enjoyable science related video I've ever seen. You are able to show and explain the beauty and intricacy of optics in a plain and simple manner. Very inspirational.
Wow I just noticed the time scales at the bottom in the beginning video. 1 PICOSECOND every 3 or 4 seconds? That's mind-boggling. Light would only travel 300 microns in 1 picosecond, or about the width of 3 hairs at a speed of 300,000,000 meters per second (rounded up). You guys never fail to impress. Even with multiple viewings I notice something new to be in awe of each time.
Liked it even before the video started... not disappointed! Keep up the good work and greetings from Germany!
extremely interesting, thanks for explaining it so a layman can understand
Literally tracing the path of light waves from surface of the sieve to the focal point (where light paths meet) the path is travelled by adjusting the focal depth. Zooming up as the light zooms up painting a picture of it’s path.
You should have wayy more subscribers! You're channel is a hidden gem. Thanks as always for the great content, I'm slowly putting together a concept for protein imaging method and using your videos as inspiration. :D
Please do.
Wow, you're quickly becoming one of my favorite channels here on UA-cam 🙏
One step closer to demistify the duality. Nice explanation.
That was super cool, and made me want to dive down the Wikipedia rabbit-hole, beginning with the article on photon-sieves.
Seeing these images very much reminds me of my studies in electrical engineering, when we would build circuits to manipulate the frequency domain of a signal. Except that was all one-dimensional, and what you're demonstrating is in two (or more) dimensions.
Thanks for all the time and effort you put into sharing your explorations. I'm gradually going through all of your past videos.
I just got a job at an optics place, i was interested in the subject to begin with, but now seeing your channel with all these cool projects and phenomenon im even more excited to be working with optics
Fascinating video. Thank you very much for making it. Keep it up!
that's the amazing thing, your videos are really inspiring, thanks for sharing Jeroen.
Sir, you are a national treasure.
It's remarkable how much the images in the first 40 seconds of the video remind me of the Cosmic Microwave Background Radiation.
I love your channel and i wish to learn as much information from you as possible! Thank you!!
It's amazing what you can do in your lab, always impressive logical breakdown of the tasks required. Thanks for showing this it is fascinating.
That is just so cool! I have no clue what's actually going on but still love those videos 😀
Such a brilliant concept and a beautiful video. Thanks again for sharing your work with us.
This channel is absolutely superb. On par with any university lecture I have ever had. Thank you so much for your work.
For once, someone who is performing empirical science and not parroting!
As amazing as this content is, I'm dumbfounded as to how there isn't more subscriber's to this amazing channel!
All that is left now, is to put aside everything that has been learnt about this particular topic and try to look at it with fresh eyes! Is it possible that what we are looking at is something that we weren't taught to see? I say this because I think that I see something that is different to what is normally understood...
Dank je wel voor de enorm leerzame video's met prachtige resultaten zoals deze!
Each video from you is a revelation. Thank you so much for this.
One of the greatest all time UA-cam Videos. Thank you
Wonderful! So often explanations of diffraction patterns hand wave this. Seeing you do this has clarified so much for me!
Thanks for going through all the effort to put this together so well, it's truly fascinating.
Thanks. There is so much more to learn in real demonstrations than an animation.
Stunning! I have one of those Christmas static laser dot shows in my living room pointed at the wall and ceiling for ambient light - I'll sit here for hours blurring my eyes slightly and shifting a couple microns to the left/right, the interference patterns are the same with every dot.
Fantastic! I really love your lab researches about light. Great examples for all of us.
Many of these images look very much like what my nearsighted eyes see from lights at night or floaters in my eyes looking at a blank sky.
Same for me. Everywhere I look I see light ripples. If I look at a very textured surface like carpet, it appears to moving.
Thanks for this video! It's nice to be able to see the patterns as a visual aide.
Great demonstration.
Chills, literal chills!!!
Incredible work. Please keep doing what you do and amazing us with your educational videos.
Very nice, thank you! Despite the spelling, "sieve" is pronounced with a short "i" as in "sit"
You're the teacher I always wanted to have
Thank you so much for this video! I’m a rising sophomore in college and I just got my first research position working with photon seives and this helped clear up a lot of confusion for me.
Light as fluid! Marvelous!
WOW! Incredible work .
Thank you so much! Your contributions are highlights !
Amazing stuff! You are showing light in new perspective. Thanks! Ordered and liked!
Wow this is incredible! I wish they did this kind of demonstration in high school.
Incredibly cool! Thanks for sharing
Incredible 😮, thanks!
this is so mesmerazing. thanks for the video!
Very cool and educational.
Thank you! one million times
Absolutely beautiful
That's really cool. Thanks!
Wow that is truly incredible.
Amazing! Thank you for this!
This is totally credible! Amazing stuff.
Incredible stuff keep that coming!
This is awesome, thank you
This, I think, is fantastic achievement made from almost household items! I think you act like a genius. Maybe you just open the door of a completely new generation of instruments & science!
Maybe also in telescopes engineering! I can definitely say that what you've found will not stop here! Congratulations!
i have the feeling that you could make the coolest photography lens
Well-Done & Amazing, phased-array lens.
Beautiful.
this well made video is really making...synergy occur in my brain...thankyou sir
Bloody fantastic
This belongs in physics syllabi.
Top notch content!
Just found your videos. Great stuff!
This explains why i have blurry focal point. At distance, theres some junk proteins in my eyes that cast a visible shadow but there are also smaller ones only visible as the blur pattern when I try to focus into the distance
Awesome! Thank you!
Beautiful!
Wonderbaarlijk!! Liefde van Canada!
Very cool!
This is dope bro
Extraordinary.
Great content.
Wonderful !.....cheers.
Truly interesting
Wonderful
Amazing
very, very interesting.
@0:05 Basically, the first thing I see in the morning when I open my eyes.
Yea that was pretty cool. I haven’t seen that before. I just subscribed.
Wow! Great!
This turns my stomach - viewing things that I never thought we would be able to view - things only visualized in my mind's eye. Unnerving. Thanks.
Awesome.
Who needs angels and demons when you've got real magic right in front of you! Thanks for the demonstration.
Impressive
awesome
holy shit. this is amazing
With how you can observe the diffraction pattern evolution by moving away from the holes, you can pretty much reconstruct a 3D volume slice by slice, I bet that'd be a cool thing to look at.
Fantasticus.
30 seconds in already awesome, and thinking how to use that, lol
youtube finally is starting to throw the right vids at me
The moving focal point mimics the motion of a water droplet
What would that layer sweep look like if you reverse the sieve pattern, making holes solid circles, and the surrounding regions transparent?
Interested in a 3D reconstruction using two sieves, three, four and so on? I bet the shapes with "picoresolution" layers would resemble a CT scan, and some DICOM programs (used to reconstruct 3D tissue) could provide some new insights about photons, and Light.
Thank you for the incredibly beautiful and educational content. As you were describing the relationship between focal plane height and time-of-flight I realized that in the photon sieve there is no material to slow down the light waves coming from the middle relative to the ones coming from the perimeter of the sieve, therefore the ones coming from the edges have to travel a longer way to the focal point, is this effect real, does it contribute to distortion and can it be managed?
