Abstract

The invention relates to a novel light combination prism adjusting device which comprises an optical platform, a light combination prism adjusting mechanism and a to-be-assembled optical element, wherein the light combination prism adjusting mechanism is arranged on the left side of the optical platform; the to-be-assembled optical element is arranged on the right side of the optical platform; a linear drive rod is arranged in the light combination prism adjusting mechanism to drive the light combination prism adjusting mechanism to move, and four micro motors drive the light combination prism adjusting mechanism to clamp the to-be-assembled optical element, so that a light combination prism is adjusted. The light combination prism adjusting mechanism constructed by adopting a motor and linear drive rod combined control method is flexible in motion output track, large in operating space, high in operability and high in positioning accuracy, the angle and position adjusting functions of the light combination prism are improved, and the quality and efficiency of a laser gyroscope light combination process are further improved.

Description

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