Paper Abstract

Two recently reported optical processing concepts can be exploited for realtime linear shift-invariant processing of 2-D imagery with acoustooptic devices: (1) space coordinate-to-temporal frequency conversion, and (2) time-integration spectral analysis. A pair of crossed acoustooptic cells, driven by periodic chirp wave-forms, can be used for both operations. State-of-the-art acoustooptic devices appear suitable for gigahertz rate processing of images with spacebandwidth products approaching 106.
