Intro to Fourier Optics and the 4F correlator (2012x32)

Data de estreia: Nov 12, 2012

It seems strange that a single piece of glass can compute the Fourier transform of an image, but it is true (sort of). I explore an optical arrangement known as a 4F correlator, and note the practical considerations that are rarely discussed in existing sources. http://www.imagemagick.org/Usage/fourier/
