Abstract:

Progress on real-time 1-D and 2-D spatial light modulators, optical systolic array processors, optical image processing, and distortion-invariant pattern recognition are reported. Our real-time spatial light modulator research concerns the Soviet PRIZ device and bulk acoustic-optic transducers. Novel features detailed for the Soviet device include uniform and directional spatial filtering and static image suppression or change detection. Systolic array processor research includes a new frequency-multiplexed architecture, realization of singular value decomposition and matrix decomposition algorithms. Optical image processing and pattern recognition research received major attention. A new class of nonlinear local operators including the Sobel operator were described and demonstrated. New optical feature generation techniques for distortion-invariant pattern recognition were developed. These include the generalized optical chord transformation. Our primary distortion-invariant pattern recognition research addressed synthetic discriminant functions with attention to two new efficient calculation techniques. The performance of synthetic discriminant functions for multi-class distortion-invariant pattern recognition, and initial noise performance of this optical pattern recognition algorithm. Author
