Abstract:
Coherent optical processing operations can be performed on a digital computer since the Kirchhoff diffraction integral, describing the imaging process of a lens, can be expressed as a discrete two dimensional Fourier transform. The advantages of optical processing on a computer are increased accuracy and operational flexibility. Applications of computer optical processing described herein include the calculation of aperture diffraction patterns, spatial filtering for image noise reduction, character recognition, and holography.
