DUAL-MODE ZEEMAN LASER GYROSCOPE Russian patent published in 2021 - IPC G01C19/66 

FIELD: measuring equipment.

SUBSTANCE: invention relates to gyroscopes and measuring equipment and can be used for creation of Zeeman laser gyroscopes (ZLG) operating in various modes of operation. Dual mode Zeeman laser gyroscope further comprises a second photodetector of annular laser radiation, which is double-site configured to generate two output rotation signals Cos and Sin, which input is ring radiation laser input, phase detector, output signals pulses counter and electronic switches unit configured to switch output signals of rotation Cos and Sin to input of phase detector or pulse counter of output signals as per control signal, wherein for signal generation sign-alternating support using clock pulse generator, frequency divider, the input of which is connected to the output of the clock pulse generator, and an electronic switch configured to switch to its output a signal from the clock pulse generator or a signal from the frequency divider.

EFFECT: higher accuracy of operating ZLG operating in different operating conditions.
