19 February 1988 Color Image Correlation Using A Magneto-Optic Spatial Light Modulator
Author Affiliations +
A real-time polychromatic image correlator that uses a magneto-optic spatial light modulator (SLM) device for pattern recognition based on both the color and shape of an input object is presented. The proposed system utilizes a multi-channel spectral matched spatial filter employed in a binary coherent optical correlator. Input color images are transformed into binary color coded coherent images by a color grating. The color coded images are read-out by a charge coupled device interfaced with a magneto-optic SLM. The color coded binary images are then processed by a multi-channel joint spectral matched spatial filter synthesized by monochromatic light. Pattern recognition experiments for naturally illuminated real color objects are presented.
