Abstract

Theoretical and experimental analyses of color-image pattern recognition using a multiwavelength Fresnel holographic filter (FHF) are presented. The FHF technique permits a greatly relaxed spatial-filter alignment requirement, use of a white-light source, negligible color cross talk, and high diffraction efficiency of the spatial filter.
