SYSTEM TO ADJUST PERIMETER OF ZEEMAN LASER GYROSCOPE Russian patent published in 2020 - IPC G01C19/68 

FIELD: instrument engineering.

SUBSTANCE: invention relates to gyroscopes. System for adjusting the perimeter of the Zeeman laser gyroscope includes a first mirror with a piezoelectric drive, which is included in the ring laser, having a reflecting mirror, as well as a unit of a frequency support, coils of which are included in the arms of the ring laser, and a clock pulse generator, the first output of which is connected to the input of the frequency support unit, a second mirror with a piezoelectric drive and an optical mixer included in the ring laser. System also comprises an inverter, an AC voltage amplifier, an amplifier with a controlled amplitude and phase, a synchronous detector, an integrator, an analogue-to-digital converter, unit of pulse counters of Sin and Cos signals, input of which is connected to output of optical mixer, processor, as well as digital-to-analogue converter.

EFFECT: technical result consists in providing the possibility of improving accuracy of adjustment of the perimeter of the gyroscope.
