Huygens Optics explains the Fourier transform and shows how a lens performs one optically. A DLP projector is used as a Fourier filter to do simple pattern recognition on lithographic character patterns.
HN 推薦的原因： Recommended as one of the best explanations of Fourier transforms and a clear demo of analog optical computing.
