Abstract

The invention relates to a mechanical dithering laser gyroscope light adjusting system. The mechanical dithering laser gyroscope light-combined adjusting system is composed of a light-combined prism, a photoelectric tube assembling mechanism, a controlling mechanism of the photoelectric tube assembling mechanism, an image collecting system and a data collecting system. The light-combined prism, the photoelectric tube assembling mechanism and the controlling system of the photoelectric tube assembling mechanism are used for adjusting the position of the light-combined prism and the photoelectric tube on a resonant cavity, and the light-combined prism and the photoelectric tube are controlled to be at the best positions. The image collecting system is used for collecting two beams of optical signals output by the gyroscope resonant cavity, optical signals are converted into the electric signals through the data collecting system, and information is sent to a main control computer. Semi automatic light combination function of the light-combined prism and the photoelectric tube on a laser gyroscope is achieved through cooperation of software and hardware. The mechanical dithering laser gyroscope light adjusting system can accurately and efficiently install the light-combined prism and the photoelectric tube, operation is stable and accurate, and the threshold value parameters of signal waveforms can be accurately judged and computed.

Description

technical field [0001] The invention relates to a precision assembly system, in particular to a mechanically dithering laser gyro light combination adjustment system. Background technique [0002] Laser gyroscope is an ideal device for strapdown inertial navigation system, especially in the military field, laser gyroscope occupies a pivotal position. The light combination system is an important part of measuring the angular velocity and angular acceleration of the laser gyro, and the realization of the light combination function is a difficult point in the assembly process of the laser gyro light combination system. The realization of the light combination is not only directly related to the efficiency and accuracy of the laser gyro measurement , but also directly affects the assembly efficiency of the laser gyroscope. The assembly technology of the laser gyro light combining system in my country is relatively backward, and manual methods have been used for a long time. Ma...
