WebIn optics, the Fourier transform can be used to describe the diffraction pattern produced by a plane wave incident on an optical mask with a small aperture [1]. This example uses the fft2 function on an optical mask to compute its diffraction pattern. Create a logical array that defines an optical mask with a small, circular aperture. WebFourier-transform spectroscopy is a measurement technique whereby spectra are collected based on measurements of the coherence of a radiative source, ... and in many of the cases in optics involving interferometers, is based on the Wiener–Khinchin theorem. Conceptual introduction Measuring an emission spectrum.

WebA primary objective is to give students of Fourier optics the capability of programming their own basic wave optic beam propagations and imaging simulations. The book will also be of interest to professional engineers and physicists learning Fourier optics simulation techniques-either as a self-study text or a text for a short course.
