Abstract
Abstract An acousto-optical light deflector comprised of a piezo-electric sound transducer adapted to receive a high frequency signal so as to generate ultrasonic sound waves and a crystalline sound medium coupled with the sound transducer to receive the sound waves and a beam of light so that the sound waves within the sound media forms a phase diffraction grating for the light beam. The sound transducer is preferably composed of a single crystalline lithium sulfate monohydrate and the sound media is preferably composed of Alpha -iodic acid.
