SYSTEM FOR ADJUSTMENT OF PERIMETER OF ZEEMAN LASER GYROSCOPE Russian patent published in 2016 - IPC G01R29/02 H01S3/83 

FIELD: measuring equipment.

SUBSTANCE: invention relates to gyroscopes and measurement equipment and can be used to adjust perimeter Zeeman laser gyroscope. System comprises photo receiver of radiation of ring laser, which input is input of radiation of ring laser, equipped with piezo drive and containing unit frequency and input of which is input signal alternating support, and output is connected to non-reciprocal device of ring laser, connected in its resonator. First synchronous detector, which first input is connected to output of photodetector of ring laser radiation, and second input is input signal alternating support, integrator with reset, which input is connected to output of first synchronous detector. Amplifier, which first input is connected to output of integrator with reset, and output is connected with piezo drive of ring laser, second synchronous detector, which first input is input signal of alternating support, and second input is connected to output of amplifier, integrator, which input is connected to output of second synchronous detector. Synchronous modulator, which first input is input of alternating support signal, which second input is connected to output of integrator, and output is connected to second amplifier input.

EFFECT: technical result consists in improvement of accuracy of adjustment.
