The video shows how the optical wave front of a laser beam can be shaped by means of DIY photon sieves. It also shows how the quality and sharpness of the focal point in a diffraction pattern can be influenced by the number of diffractive apertures in the photon sieve surface.

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.

@redrum5053 2 года назад

I'm sorry?! This may be the most stunningly beautiful representation of light I have ever seen! Thank you so much!

@Alexander_Sannikov 2 года назад

what a gem of a channel. the youtube algorithm has finally decided to recommend it to me.

@ViceChief 3 года назад

Definitely the coolest, most interesting, and most optical thing I've seen on RU-vid this year! Thanks again for an excellent video and for your continued presence here.

@blacklistnr1 2 года назад

"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

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!!

@fzigunov 3 года назад

Just found this channel! You're amazing, please keep it up, we need more of this highly technical stuff in youtube!!

@Pyroguy92 3 месяца назад

This might be the greatest physics video on RU-vid. And that says a lot...

@vincenzomartorana2625 3 года назад

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.

@halonothing1 Год назад

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.

@jakobriedel3725 3 года назад

Liked it even before the video started... not disappointed! Keep up the good work and greetings from Germany!

i want to sleep. but i went the rabbit hole of your videos and I can't stop. fascinating works

@MrDragonFoxAI 4 года назад

extremely interesting, thanks for explaining it so a layman can understand

@denzali 2 года назад

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.

@halonothing1 2 года назад

It's remarkable how much the images in the first 40 seconds of the video remind me of the Cosmic Microwave Background Radiation.

@superciliousdude 3 года назад

Fascinating video. Thank you very much for making it. Keep it up!

@MelindaGreen 2 года назад

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.

@jajwarehouse1 2 года назад

Same for me. Everywhere I look I see light ripples. If I look at a very textured surface like carpet, it appears to moving.

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.

@pdelong42 Год назад

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.

@PeterMilanovski 2 года назад

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...

@gatyair82 3 года назад

@mariodistefano2973 2 года назад

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!

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

@franciscojosetorcalmilla9462 Год назад

Fantastic video! Thanks for sharing. Could you tell me how do you obtain the position and diameter of each hole? Is there an algorithm that converts the Fresnel lens to a photon sieve? Any references would be great. Thanks!

@besenyeim 2 года назад

Awesome. Now I wish to see a water bath analog of this. Drilled or etched holes in a plate. Plate in a container, height adjusted to put focal point on surface, and just hit the bottom of container. How did you generate the patterns?

@SpaceCadet4Jesus 2 года назад

@0:05 Basically, the first thing I see in the morning when I open my eyes.

@TiagoTiagoT 2 года назад

What would that layer sweep look like if you reverse the sieve pattern, making holes solid circles, and the surrounding regions transparent?

@raresnetboy 3 года назад

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?

@evilotis01 2 года назад

holy shit. this is amazing

@Metaldetectiontubeworldwide 2 года назад

Whaaw very intresting video's you make , sir well done ! Realy enjoy them , and still learn alot . I was wondering thought , for what they are used ? These photon sieves? I am a hobby astronomer , on a very small and limited budget 😄 . Are they a bit like a 'Bathinov' mask used to focus on stars , with photography lenses. But the used for the microscopic ? Or can one use this sieves to do that to stars aswell . Because the fact they focus all color in phase , made me curious ? If it could not perfect the way i image my astro photos ? Grtzz from the Netherlands Johny geerts P.s. are you related to the inventor of the telescope ? (Awesome you are in the same field )

@kooskroos 3 года назад

How did you recreate the paterns from the paper? Or did they share it with you?

@HuygensOptics 3 года назад

I used a high-resolution image that I found using Google Images. Currently I'm modifying my zone plate program to generate sieves as well.

@AnonTen Год назад

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.
