ELECTRO-OPTICAL SIGNAL PROCESSING TECHNIQUES FOR PHASED ARRAY ANTENNAS.

Abstract

The investigation of array antenna electro-optical signal processors continues with emphasis placed on the development of wideband solid light modulator. Theoretical considerations are presented describing the characteristics of both longitudinal and shear mode solid light modulators operating at 80 and 100 mHz. These characteristics include the effects of applied voltage and internal refraction on the light modulation and lead to a nomographic method for determining optimal transducer dimensions, in the direction of light propagation, under various conditions of interest. The electrical loads presented to the driver by specific idealized transducers have been examined, and results are presented which are useful in driver design and in the determination of the power dissipated in the modulator during CW operation. From these theoretical considerations the advantages of the longitudinal mode of modulator operation over the shear mode become evident and justify the need for parallel investigation of both modes in the experimental program.
