Paper Abstract

This paper describes realizable acousto-optic configurations for the implementation of phased array beamformers. The simple system is capable of generating a distribution of wideband radio frequency (RF) signals with controlled phases. A laboratory demonstration model of the acousto-optic beamformer was built using a pair of Bragg cells and a 10-channel fiber-detector array. Experimental results show that a large phase excursion is obtainable simply by tuning the frequency of the control signal.
