由于双光楔系统可以精确调整光轴的指向，而且具有结构简单紧凑、调整速度快、偏转角度大的优点。为了满足某产品的需要，实现同心圆和Z 字型的光轴调整轨迹。本文根据现有理论，通过建立光轴偏转角度与双光楔转动角度关系模型，推导出对应公式，并结合Matlab 仿真、拟合和实际的产品测试，设计出了利用ARM 与计算机控制双光楔来调整光轴指向的方案。结果表明，该方案光轴指向调整的误差小于0.5°，能够实现预期的轨迹，满足实际产品的需求。

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.
