针对电动二维转镜在进行光学转像或扫描时产生的转角值与像移值不一致的现象，提出了一种软件修正读数的方法。利用欧拉角知识分析了二维转镜的运动姿态，建立了二维转镜的运动模型，推导出二维转镜旋转矩阵。根据平面光学知识得出出射光线的俯仰角与方位角，并通过软件对俯仰方位读数进行修正。验证试验结果表明，修正后二维转镜在俯仰方位两个方向上的读数精度达到4秒。

Aiming at correcting two-dimensional rotating-mirror’s reading in optical scanning or rotation,in this paper, reading correction method based on software is proposed. Using Euler Angle knowledge,the moving posture of two-di-mensional rotating-mirror is analyzed, a motion model of two-dimensional turntable is established, and mirror’s rota-tion matrix is deduced. According to the optical knowledge, emergent ray’s pitch angle and azimuth angle is deduced. Readings in the horizontal and vertical direction are compensated by software. The experimental results show that mea-surement accuracy of this method is 4 second in the direction of horizontal and vertical.
