Optics fourier transform

WebThe 4f correlator is in essence an optical relay that usually consists of two lenses. The input plane is one focal length in front of Lens 1 while the output plane is located one focal length after Lens 2. In between the two lenses, we have the Fourier plane. Here is where we have the Fourier transformation of the object placed at the output plane. WebOptics. Menu. More Info Syllabus Calendar Lecture Slides Video Lectures Assignments Projects Exams ...

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 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.
