DEVICE FOR REGULATING PERIMETER OF FOUR-FREQUENCY ZEEMAN LASER GYROSCOPE Russian patent published in 2021 - IPC G01C19/66 G01R29/02 H01S3/86 

FIELD: measuring technology.

SUBSTANCE: invention relates to gyroscopes and measuring technology and can be used for regulating the perimeter of a four-frequency laser Zeeman gyroscope. The invention relates to a device for adjusting the perimeter of a laser gyroscope, said device comprising a photodetector for the output radiation of an annular laser equipped with four mirrors, the first and three of which are provided with a piezodrive, the third being reflective, the fourth is provided with an optical mixer, which forms the output radiation of the annular laser, as well as with a frequency support unit, the coils of which are connected to the arms of the annular laser, and with a synchropromuls generator, the first output of which is connected to the input of the unit of the frequency support, as well as a unit for counterwave pulse counters of two longitudinal modes, a processor, a digital analog converter and an amplifier.

EFFECT: technical result is increase in the precision of the perimeter of a four-frequency Zeeman laser gyroscope.
