摘要: 本文基于一种多波段图像融合系统, 对系统光轴平行性装调技术进行研究。系统为五光轴平行系统, 包括白光模块、微光模块、短波红外模块、长波红外模块、激光测距模块, 通过计算得到精度最高的为微光模块, 精度为 32.09., 即平行性偏差小于 32.09.不影响系统使用。装调时采用光轴中心与平行光管十字靶板中心对准的方法, 得到的图像为最大图像尺寸的 99.89%, 对图像信息获取不产生影响。最后用搭建好的平台对系统进行实验验证, 实验证明平行性最大偏差为 9″, 小于系统最大允许误差, 所以得出结论该装调方法对类似产品的装调具有一定参考价值。

This article is based on a multiband image fusion system and studies the alignment technology of the parallelism of the optical axis of the system. The five-axis parallel system includes a white light module, low light level module, short wave infrared module, long wave infrared module, and laser ranging module. The lowest light level module with the highest accuracy was 32.09. A parallelism deviation of less than 32.09 does not impact the system's usability. During installation and adjustment, the optical axis was aligned with the center of the collimator cross-target plate. This alignment produced an image size that is 99.89% of the maximum possible, which does not hinder the acquisition of image information. Finally, the system is verified experimentally using the developed platform. Experiments proved that the maximum deviation of the parallelism was nine, which is less than the maximum allowable error of the system. Therefore, this assembly and adjustment method had a certain reference value for the assembly and adjustment of similar products.
