SYSTEM TO ADJUST PERIMETER OF ZEEMAN LASER GYROSCOPE Russian patent published in 2020 - IPC G01R29/02 

FIELD: measuring equipment.

SUBSTANCE: invention relates to gyroscopes and measurement equipment and can be used to adjust perimeter Zeeman laser gyroscope. System for adjusting the perimeter of the Zeeman laser gyroscope further comprises a second mirror with a piezoelectric drive and an optical mixer included in the annular laser, pulse frequency divider by two, the input of which is connected to the output of the clock pulse generator, and the output is connected to the control input of the second mirror with the piezoelectric drive, series-connected pulse counters of signals Sin and Cos for current and previous clock cycles of clock pulse generator, which input is connected to output of optical mixer, a processor configured to count the difference between pulses of signals Sin and Cos over the current and previous clock cycles of the clock pulse generator and generating a control signal proportional to said difference, digital-to-analogue converter and amplifier, the output of which is connected to the control input of the first mirror with a piezoelectric drive.

EFFECT: high accuracy of adjusting the perimeter of the Zeeman laser gyroscope.
