Abstract

Computer simulation and experimental results of computer-generated hologram (CGH) spatial filters applied to the deblurring of color images in a dispersed white light optical processor are presented. Significant performance can be achieved with moderate resolution images and 1-D processing operations. Color smear and multiband filter/signal spectrum size mismatch limit applications involving large space–bandwidth images and/or 2-D processing operations with the dispersed system configuration. The flexibility of the CGH spatial filter fabrication technique, combined with the added processing dimension of wavelength and the inherent ability to reduce coherent artifact noise, make this processing scheme attractive for many image processing applications.
