Description

Technical field [0001] The invention relates to a precision assembly system, in particular to a mechanical dithering laser gyroscope combined light adjustment system. Background technique [0002] Laser gyroscope is an ideal device for strap-down inertial navigation system, especially in the military field, laser gyroscope is more important. The combining light system is an important part of measuring the angular velocity and angular acceleration of the laser gyro. The realization of the combining light function is a difficult point in the assembly process of the laser gyro combining light system. The realization of the combining light is not only directly related to the efficiency and accuracy of the laser gyro measurement , But also directly affect the efficiency of the assembly of the laser gyro. The assembly process of the laser gyro light synthesis system in my country is relatively backward, and manual methods have been used for a long time. Assembling by manual methods, ...
