Abstract

The development of an optical correlator system and flight tests to be conducted from a remotely piloted vehicle (RPV) are described. The optical processor is based on laser gyroscope construction techniques and relies on 128 X 128 reflective-mode magneto-optic spatial light modulators for both the input image and spatial filter insertion. The input image is obtained from a visible camera in the nose of the RPV. The processing system incorporates Kalman's invariant filters. The output of the correlator is through a 128 X 128 high speed CCD camera. The correlator system also includes image processing and all electronic drivers. The optical package occupies a volume less than 25 in³ while the whole processor package is less than 1 ft³ and weighs less than 40 lbs, and is ruggedized for temperature, shock, and vibration. The RPV, Eglin Air Force Base test range facilities, tower tests, telemetry, and training set acquisition are discussed.
