Research and Design of PROM Coherent Optical Processor.
Abstract
This program produced a design for a coherent optical image processor utilizing a PROM(s). The PROM Coherent Optical Processor or PCOP is a subsystem of the USAETL Hybrid (Optical/Digital) Image Processor. The design and supporting analysis tasks are detailed in the report. The purpose of development of this processor is to evaluate automatic image feature extraction algorithms. The PCOP is a two PROM Fourier plane filter processor which operates in the following manner. The first PROM is the input image plane. Imagery is scaled through a lens system and then manipulated in intensity space at the input PROM. The image transform is taken next in the processing sequence and then filtered at the second PROM. Filters are generated with a laser optical scanner. The reconstructed image is produced on a charge integrating camera and displayed on a CRT. Image quality and data throughput were determined and the PCOP design was made to insure the output quality was compatible with the USAETL program objectives.
