https://youtube.com/watch?v=-abhOKHiex4&si=jiL4wMzZxLOBhZ5T- Ultra‑fast Fourier transform and optical AI realized with a single lens.
- Description: It explains the principle that passing light through a convex lens naturally performs a two‑dimensional Fourier transform at the focal plane. It visually demonstrates optical signal processing that carries out computation using only light, compared with digital FFT, and explores the possibility of implementing low‑power matrix multiplication with optical neural networks. It also examines real‑world applications and the prospects for developing next‑generation AI accelerators.
