Description

technical field [0001] The invention relates to a laser gyro temperature compensation control device, and also relates to the application of a temperature control device in the laser gyro temperature compensation. Background technique [0002] As a photoelectric inertial sensitive instrument with advanced principle, laser gyro does not need the high-speed rotor necessary for electromechanical gyro, and its performance advantages are quite obvious. It is an ideal angular velocity sensor for a new generation of high-sensitivity, high-precision, and large dynamic range strapdown inertial systems. , is so far the only non-electromechanical medium-high precision inertial sensitive instrument that has really achieved fruitful practical applications in the field of inertial technology. The total reflection prism laser gyroscope is a new type of laser gyroscope, which avoids the complex coating process of the traditional reflector laser gyroscope, and has the advantages of stable pe...
