A new 3f multiple hybrid opto-electronic roal-time pattern recognition system is introduced. A planar microlens array is used to generate multiple Fourier transforms of the input patterns. The matched filters are binary phase-only filters fabricated by standard VLSI techniques on a fused quartz substrate. This system performs the correlations of the input patterns and many reference images.
