Because the double-wedge system can accurately adjust the orientation of the optical axis, it has the advantages of simple and compact structure, fast adjustment speed, and large adjustment angle. In order to meet the needs of a certain product, optical axis adjustment trajectories of concentric circles and zigzags are realized. Based on the existing theories, this paper establishes the corresponding formula by establishing the relationship between the optical axis deflection angle and the bi-wedge rotation angle model, and combines the Matlab simulation, the fitting and the actual product testing, and designs the use of ARM and computer-controlled bi-optical wedges to adjust the orientation of the optical axis. The results show that the error of the optical axis pointing adjustment of the scheme is less than 0.5°, and the expected trajectory can be achieved to meet the requirements of actual products.
