Webnot the only thing one can do with a Fourier transform. Often one is also interested in the phase. For a visual example, we can take the Fourier transform of an image. Suppose we … 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.

WebMay 21, 2012 · No we don't see Fourier transforms--- we see classical (geometrical) optics, which is light propagating along geometric paths in the limit of small wavelengths. This limit makes it so that the light we get from a source is refocused into a point at a location corresponding to the source, there is no Fourier transform involved. WebThe Fourier transform of this signal is the equivalent of breaking the light into it's component parts of the spectrum, a mathematical spectrometer. One simple example application of …
