Paper Abstract

JPL has developed a compact portable 512 x 512 Grayscale Optical Correlator [1-4] by integrating a pair of 512 x 512 Ferroelectric Spatial Light Modulator (FLCSLM), a red diode laser, Fourier optics, a CMOS photodetector array. The system is designed to operate at the maximum speed of 1000 frames per second. A FPGA card was custom programmed to perform peak-detection post-processing to accommodate the system throughput rate. Custom mechanical mounting brackets were designed miniaturized the optics head of the GOC into a 6” x 3.5” x 2” volume. The device driver HW/SW is installed in a customized PC. The GOC system’s portability has been demonstrated by shipping it to various locations for target recognition testing.
