| 摘 要： | 针对数字式二维转镜在光学转像时产生的转角值与实际像移不一致的问题,提出了一种运用光学矩阵修正读数误差的方法。根据二维转台对准读数检测原理建立数学模型,得出修正后的出射光线的俯仰角及方位角。为了验证上述模型的正确性,采用高精度经纬仪对修正后的出射光线方向进行校对。经实验对比,该方法在不提高加工安装精度的情况下修正了二维转镜的读数误差,其精度达到4″。

| Abstract: | Aiming at correcting the digital two-dimensional rotating-mirror's angle and the actual image motion reading inconsistencies on optical scanning, in this paper reading correction method is proposed based on optical transmission matrix. First of all, according to the principle of two-dimensional turntable alignment readings detection, mathematical model is set up. The corrected pitch angle and azimuth of the emitted light is obtained. In order to verify the model, the emergent light direction for proofreading is revised by using high precision theodolite. In the experiment, this method improves the two-dimensional mirror reading error to 4" without increasing the precision of installation. |
