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 polygonal laser gyroscope monoblock optical channels 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 thermostabilization 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 a cooling radiator. At the same time, in the amount of, at least, two to the optical channel, grooves of a given depth and geometry are created in the metal base, forming convex zones in the metallic base, which are in thermal contact with the bottom surface of the polygonal monoblock relative to the local heating source - the Peltier element and provide zone equalization of the temperature gradient in the working zones, which ensures compensation of the thermal imbalance of the optical channel working zones in the amount equal to the amount of the generated convex zones. The contour of the polygonal monoblock is covered by a groove of a given depth and geometry to exclude the general influence of the metal base on the temperature distribution in the convex zones and to provide the required temperature gradient in the compensation zone with respect to the local heating source.

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