Thank you for publishing this course. Very grateful.

Im a CS major but I found this really cool. wondering if i should get a minor in physics lol

Can't believe I got scammed by the guy selling Fourier lenses at the corner of the street last week.

Thanks a lot 👍

love from india

thank you sir

I wish my uni explained concepts like you. Instead they decided to explain the same idea with approximately 135 ppt slides (no joke). My attention span and love for optics had almost dissipated. Thank you

LASER: Light amplification by stimulated emission of radiation

What is plane of polarisation and plane of incident in this explaination? Kindly if anyone can explain with diagram

What are the full forms of DC and AC in optics?

Intriguing video! I wonder, in the bottom figure at 11:32, how the pattern on the panel at (f) will change if you shift (Left or right) the position of the object grid?

How does it work?

Thank you for the series. Helped me a lot. Love from INDIA

If only we had teachers like this.

We have a positive lense in our eyes, so we are always looking at the fouriere transform, just rarely look at coherent light source.

Thank you so much for the great lesson, it would be grateful for me if you can share any related books you referred.

Thank you so much for this series!

On slide 6, where does the Theta variable come from after calculating the fourier transform?

This is, by far, the best explanation of birefringence I have ever seen.

great！

I am so happy. This was the most clear introduction to fourier optics I have come across.

All thumbs up! Very clear and useful 👍

at 2:34, you talk about the "electrically conductive components of a polarizer". Can you explain what that means? Are you talking about linear polarizers that can be purchased as plastic sheets, or another type of polarizer?

thumbs down for car sounds and all the distractions.

Dear sir as you mentioned in the first part of the video are Fourier optics and electromagnetic/quantum optics same? Thanks

At 7:34, you talk about the "two subcomponents of a polarized photon". Are you talking about the electric field and magnetic field components of the electromagnetic wave that are orthogonal to each other, or are you talking about two light rays that are polarized along different axes, i.e. vertical and horizontal? At 9:04, you talk about a quarter wave plate turning linearly polarized light into circularly polarized light because it delays the phase of one of the photons by 90 degrees; but you don't explain how "circularly polarized light" is the result of that, unless you are simply stating that polarized light that has a component that is 90 degrees out of phase is circularly polarized light. But you still don't explain why it is given that name.

can you explain please how this works

bro, 10:59, you made so much sense, I totally understand the essence of this pinch-off staff,even I just started to learn Semi-Conductor after you released this vedio 2 years. Thank you soooooooooooomuch

This helped a lot... thank you

Badass

But isn't the diffraction/ Fourier-Transform happening by the object itself. The lens is just focussing?

Is there a way or do they have a liquid form of this or can you melt the plastic of poloierized to turn it to liquid form

A nice explanation on filtering

I have a graduate degree in optics and photonics and gotta tell you, you have some really amazing explanations that help the intuition beyond the math. For example, the Ohmic loss of a metal mirror vs a lossless glass mirror due to the glass being a dielectric. I never thought about it that way until now. But a consequence is that now I don't feel I understand how enhanced aluminum mirrors work---I'm going to have to rethink that.
