METHOD OF COMPENSATING FOR THERMAL BENDING AND DEFORMATION OF LASER GYROSCOPE MONOBLOCK OPTICAL CHANNELS Russian patent published in 2017 - IPC G01C19/66 

FIELD: physics.

SUBSTANCE: method of compensating for the thermal bending and deformation of optical channels of a polygonal laser gyroscope monoblock is based on the installation of an optically transparent monoblock, the operating mode of which is achieved using a micro-power semiconductor laser diode equipped with, at least, one Peltier element for the thermostabilisation of the radiation regime of a laser diode located inside the optical circuit, formed by a set of optical laser gyroscope channels, on a metal base with functions on cooling radiator. At the same time, at the base of the monoblock, special grooves of a given depth and geometry are created, but not interlocked with the optical channels, which, prior to mounting, are filled with heat-conducting paste to the level of contact with the metal base and provide a zone equalization of the temperature gradient in the working zones from the source of local heating - the Peltier element. The thermal conductivity of the paste should be several times higher than that of the metal base, which compensates for the thermal imbalance of the working zones of the optical channels in the amount equal to the number of created slots.

EFFECT: compensation of thermal bending and deformation of optical channels of a polygonal laser gyroscope monoblock and ensuring its operability at high and low ambient temperatures.
