FIELD: optics.
SUBSTANCE: laser gyroscope has a polygonal optical monoblock with optical channels, totally reflecting mirrors and semitransparent mirror. Optical radiation source used is a semiconductor laser. Optical monoblock is made in form of equilateral regular hexagon, at geometric centre of which there are thermoelectric module and a radiation source, being in thermal contact with radiator thermoelectric module. Totally reflecting mirrors and semitransparent mirror, made in form of interference of converter in form of a lens, adjoin directly to faces of optical monoblock. Linear thermal expansion coefficients of materials of totally reflecting mirrors of radiant energy and semitransparent mirror are equal or close to linear thermal expansion coefficient of optical monoblock, and semitransparent mirror is arranged in adjustment appliance.
EFFECT: technical result consists in compensation of temperature error, ensuring operation at high and low temperatures.
