摘　　要：针对现有光学主被动探测多轴一致性检测精度不高的问题,研制了一种光轴检测精度优于10μrad的多轴一致性检测装置.该装置基于大口径平行光管法实现对多个光轴的一致性检测,涵盖了可见光、激光及红外等多波段光学系统的多光轴一致性.该装置出光口径为450mm,焦距实测值为4556mm.通过对装调过程中可能产生误差的环节进行分析,最终计算得到的光轴检测合成误差(3σ)约为7.5μrad.通过经纬仪沿俯仰和多个随机角度方位将光线打入检测装置进行实测,光轴检测精度约为8.9μrad,与理论分析得到的检测精度仅偏差1.4μrad.最后,根据每种误差形式,给出了减小误差的具体措施.To address the issue of low testing accuracy in the existing multi-axis optical consistency systems,a multi-axis consistency testing device was developed with an optical axis testing precision better than 10μrad.The large-aperture collimator method was adopted to assess the consistency of the multiple optical axis,including visible,laser,and infrared wavebands.The device with a light output aperture of 450 mm has a measured focal length of 4556 mm.By analyzing the potential error sources during the installation and commission process,the synthesized optical axis testing error(3σ)is approximately 7.5μrad.The actual testing accuracy,verified through a theodolite measurement at multiple random angles in both elevation and azimuth,is about 8.9μrad,showing a deviation of only 1.4μrad from the theoretical analysis.Finally,specific measures to reduce errors for each error type were proposed.
