LASER GYROSCOPE Russian patent published in 2013 - IPC G01C19/66 

FIELD: measurement equipment.

SUBSTANCE: laser gyroscope includes a triangular optic monoblock with shaped optic channels, mirrors of full reflection of radiant energy, a semi-transparent mirror, a prism and an optic emission source based on a semiconductor laser. In order to provide a single-mode radiation condition of the semiconductor laser, the latter is equipped with an additional external optic resonator in the form of a semi-sphere that is truncated symmetrically relative to central symmetry axis on both sides to thickness of the optic monoblock and covered with a reflective coating. Along its longitudinal symmetry axis there formed are two optically transparent holes at the level coinciding with the level of optic channels of the monoblock, which implement in the resonator of the emitter a longitudinal optic channel that is a continued part of the optic channel of the monoblock, thus closing an annular optic scheme of the monoblock.

EFFECT: higher reliability of the design and its manufacturability.
