针对在光机装校阶段, 分析光学件和金工件的设计、加工和装配的累积误差对图像配准精度的影响。首先, 分析在光机装校时采取主观评价方法评价图像配准质量的原因; 其次, 具体分析物镜的焦距和畸变误差、光轴一致性误差和探测器安装面误差对图像配准精度的影响。通过分析误差产生的原因, 提出在光机装校时的解决办法。

This paper aims at, in the assembly stage, the analysis of errors on image registration accuracy accumulated in optical parts and metal parts design, processing and assembling. The first analysis takes subjective evaluation method to evaluate the quality of image registration. Secondly, the paper specifically analysis’s the focal length of the object lens and distortion error, light axis consistency error and a detector mounting surface errors on the accuracy of image registration effect. Through the analysis of the error sources, the solution is proposed in the assembly.
