"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 optics is principally based on the ideas of convolution, spatial correlation, and Fourier transformation. Making use of these central ideas, it leads to a simple but deep understanding of the way an optical field is transferred by an optical system from an input plane to an output plane. WebMay 30, 2016 · The ability to implement the Fourier transformation in a simulation is a useful functionality for a variety of applications. Besides Fourier optics, we use Fourier transformation in Fraunhofer diffraction theory, signal processing for frequency pattern extraction, and image processing for noise reduction and filtering.
