DEVICE FOR DEFLECTING BEAM Russian patent published in 1995 - IPC

FIELD: optical instrument engineering. SUBSTANCE: device has light source 1, reflector 2, sweep generator 7, and round-shaped piezoelectric plate 3, which is fixed rigidly inside case 6. Control electrode 5 is applied to one side of the plate, and the other side of the plate is connected with flexible metal substrate 4. Reflector 2 is attached to center of piezoelectric plate 3 from the side of control electrode 5 at specific angle to the source. Sweep generator is made in form of cine oscillation generator. EFFECT: improved accuracy; improved reliability of operation. 3 dwg
