摘　　要：针对多传感器光电系统存在的光轴平行性调校需求,介绍了一种光轴跨距较大的高精度校轴仪及其工作原理。该装置核心为卡赛格林系统,其主镜采用了一种新型粘接与光学定中心方案用于解决受力变形,实际变形结果验证了该方案的可行性。通过精确调校卡赛格林系统以及检测光路的光轴平行性,文中的校轴仪理论检测精度可达10″以内,因此其配合大口径离轴反射式平行光管使用时,能实现对多传感器光电系统光轴平行性的高精度调校。In order to adjust the optical axes in the multi-sensor electro-optical system ,a kind of new calibration device with a wide span of spectral-axes is introduced ,of which working princi-ple are described in detail .The Cassegrain system is the core of this device ,whose primary mirror uses a new kind of adhesive and optical-centering techniques to relieve deformation ,and the experimental results verify the feasibility of the proposed techniques .In addition ,by pre-cisely adjusting the Cassegrain system and multi-axes of detecting optical paths ,the detection precision of this new calibration device can up to 10" theoretically .Therefore ,using the pro-posed device and the large aperture off-axis reflective collimator ,the parallelism of optical axes of multi-sensor electro-optical system can be calibrated precisely in different environments .
