METHOD OF INCREASING ACCURACY OF USEFUL SIGNAL OF RING LASER Russian patent published in 2016 - IPC G01C19/70 

FIELD: physics.

SUBSTANCE: method of increasing accuracy of the useful signal of the ring laser consists in the fact that rotational vibrations of the housing of planar optical resonator relative to the body of gyroscope by means of vibration frequency support, operating at resonant frequency of vibrating suspension, effect on the useful signal is compensated minus signal of relative movement of the housing of planar optical resonator at each step of retrieving information at the rate at least six times greater than the rate of vibration frequency of resultant signal. Herewith selection of higher types of oscillations in zone of the neck of electromagnetic field of planar optical resonator is made. Reflecting elements, which contribute to change angle of direction of laser radiation in optical channel installed in the body of planar optical resonator, are arranged symmetrically relative to body lengthwise axis of the planar optical resonator. Effect of distortion of perimeter of the optical channel on the useful signal is minimised by providing dependent or independent from each other changes of position of said reflecting elements relative to the body of the planar optical resonator by a value corresponding to changes in optical channel perimeter.

EFFECT: technical result consists in increasing accuracy of the useful signal of the ring laser.
