Acousto-optic deflector-locked OF CRYSTAL IN SPACE

摘要

The invention relates to acousto-optics and laser technology, in particular to broadband acoustooptic deflectors used to control the spatial position of the optical beams. The technical result in the implementation of the claimed utility model is to provide effective automation diffraction acousto-optical deflector over a wide range of operating frequencies. The technical result is achieved in that the acoustooptic deflector-locked position of the crystal in a space containing acoustic line, formed as a body with a photoelastic properties, piezoelectric transducer located on the end face of the acoustic duct, wherein the input piezoelectric transducer is connected to a control voltage source, the scavenger deposited on a face acoustic line opposite the face with the piezoelectric transducer, a piezoelectric system further comprises angular displacement, upon which the turbo, and the detection unit changes the frequency control voltage, the input of which is connected to the second output of the control voltage source, and an output - with a piezoelectric system angular displacement, and the piezoelectric system is the angular displacement is, for example, as a disc fixed to the piezoelectric motor of n glued piezoelectric cylinders connected to the sliding contact of the detection unit changes the frequency control voltage, and the detection unit changes frequently you control voltage is formed as a frequency discriminator whose output is connected to the input of the DC amplifier.
