Optical fourier transform
WebAs the spatial Fourier transform reveals the far field distribution, as explained above, it is apparent that by using a lens one can reveal that pattern without applying a large propagation distance. By placing an optical aperture in a Fourier plane, one can effectively modulate the spatial frequency spectrum. WebJul 19, 2024 · We will discuss a few Fourier Transforms that show up in standard optical systems in the first subsection and use these to determine the system resolution, and then discuss the differences between coherent and incoherent systems and impulse responses and transfer functions in the second subsection.
