LASER GYROSCOPE Russian patent published in 2022 - IPC G01C19/66 

FIELD: laser technology; navigation.

SUBSTANCE: invention relates to the field of laser technology and navigation systems, to strapdown inertial navigation systems. The device contains: a polygonal optical monoblock with optical channels; mirrors of full reflection of beam energy; a converter for retrieval of information in the form of beam energy of an interference pattern, combined with a semitransparent spherical mirror; a semiconductor laser is used as an optical radiation source. For creation/pumping of counter flows of beam energy in an optical circuit of the monoblock, an outer optical divider is used, outputs of which, based on optical fibers, are connected to two additionally formed optical channels in the monoblock and located in a plane of optical channels, axes of which form, together with axes of interfaced optical channels, an angle less than aperture of the interfaced optical channel, and the end of output optical fibers of the divider is made in the form of a Bragg lattice for a working wavelength of the semiconductor laser.

EFFECT: creation of a monoblock laser gyroscope with a passive optical circuit, reduction in temperature instability, increase in the efficiency of use of energy of a semiconductor laser, provision of more stable performance.
