ACOUSTIC-OPTICAL DEVICE WITH VARIABLE ANGLE OF PIEZO INVERTER

摘要

FIELD: physics.SUBSTANCE: claimed device comprises acoustic-optical crystal, piezo inverter and control element to vary inclination angle between said crystal and said inverter and rigidly coupled therewith. Control element is composed of two prisms in contact with each other by two planes and arranged to turn relative to each other about axis perpendicular to crystal surface and axis perpendicular to prisms contact planes.EFFECT: higher accuracy of setting the angle of piezo inverter inclination to acoustic-optical crystal.2 cl, 3 dwg
