The results of the electro-optical phased array signal processor research program during the past period are presented. The spatially multiplexed system experimental response for a weighted and unweighted aperture distribution is shown graphically and with photographs. The theoretical and experimental system response for a Hamming type aperture weighting function to signals on and off boresight is presented. An experimental sidelobe suppression of 28 db is demonstrated. A Schlieren photograph of the ultrasonic beams within the light modulator is included. The time multipex system signal simulator implementation and block diagram are presented. The method utilized for phase alignment of the simulator is discussed.
