Description

technical field [0001] The invention relates to the field of laser gyroscope light combining, in particular to a photocell adjustment device used for laser gyroscope light combining assembly. [0002] technical background [0003] Laser gyroscopes have the advantages of fast response ability, wide dynamic measurement range, good linearity, small dynamic error, high precision and high reliability, and are widely used in strapdown inertial navigation systems. The light combining of the laser gyro refers to the precise adjustment of the position of the light combining prism and the photocell during the manufacturing process of the laser gyro, so that the output of the laser beam running in the resonant cavity will interfere, and the frequency difference information corresponding to the angular velocity of the gyro can be accurately obtained. The adjustment of the photocell is an important part of the laser gyroscope light-combining assembly. At present, the photocell adjustment ...
