  • Acousto-optical deflector
    Patent number: 5122898
    Abstract: An acousto-optical deflector disclosed, comprising, two crystals and two piezoelectric transducers associated respectively with the crystals and controlled by a variable frequency RF signal for generating, in the crystals, ultrasonic waves of the same frequency. The crystals are aligned along an acoustic axis for receiving in the aggregate a single incident light beam and generating a single diffracted beam and being spaced apart from each other by a gap creating an acoustic discontinuity without deforming the light beam.
