Can you expand on that? Or have some reading for that?
I guess it makes sense, light is a wave and anything even vaguely to do with waves seems to end up with Fourier transforms, but still I'm curious about the details
- infogulch 3y agoHow about a practical demonstration of optical Fourier transforms? https://www.youtube.com/watch?v=Y9FZ4igNxNA https://www.youtube.com/watch?v=Y9FZ4igNxNA
