In this video, I explain how lenses perform Fourier transforms by canceling the phase due to free space propagation. I use both the concepts of angular spectrum and Fresnel propagation, and the awesome result is that a lens performs a fourier transform if it is placed a distance of 1f away from an object, and the observation plane is 1f away from the lens.
This is part of my graduate series on optoelectronics / photonics, and is based primarily on Coldren's book on Lasers as well as graduate-level coursework I have taken in the EECS department at UC Berkeley.
Hope you found this video helpful, please post in the comments below anything I can do to improve future videos, or suggestions you have for future videos.
