摘　　要：针对大口径折反射红外光学系统设计过程中正主、次镜的像差为单独校正,无法实现高精度调试的问题,提出设计一套可见光波段辅助装调镜的方法,辅助镜用于补偿主次镜之间的像差,完成高精度装调。辅助透镜研制过程中,严格控制加工精度,减少对系统精度的影响。采用ZYGO干涉仪对系统进行了调试,波像差实际值为0.3λ,设计值0.14λ。最后,更换中继透镜组,光学系统成像质量达到红外搜索跟踪系统的要求。During the designing process for large diameter catadioptric infrared,the aberrations of primary and secondary mirrors are calibrated separately,which makes the precise alignment difficult.For this problem,an assistant alignment lens used for infrared optical system was designed,which could compensate the aberrations to accomplish system alignment with high-precision.The manufacture precision of assistant alignment lens was exactly controlled to reduce error caused by itself in manufacturing process.The designed wave aberration data of system is0.14λand the practical data is 0.3λafter operated using ZYGO interferometer.At last,the secondary imaging lens was used in stead of assistant alignment lens.The result shows that the image quality of the optical system can satisfy the demand of infrared search and tracking system.
