| 摘 要： | 在地面的目标探测光学系统多采用大口径(500 mm)同轴光学系统的前提下，系统探测的大视场和宽光谱就成了亟待解决的问题。设计了附带小口径球面透射校正镜组的折反式光学系统，利用该校正镜组校正了系统由于大相对口径、大视场和宽光谱带来的像差，使系统达到了预定的指标要求。其中只有主反射镜面形为二次非球面，设计参数也易于加工。在相应的实例要求下，用ZEMAX光学设计软件进行了优化评价，并给出了该系统的对星观测结果。该光学系统设计的口径为Ф750 mm，相对孔径为1:1.32，视场为4 ，光谱范围为500~800 nm，系统实际探测能力在15 Mv以上。该系统结构简单，均采用普通玻璃材料，成本低，成像质量良好。

| Abstract: | In the optical system,the apertures of most of target detecting systems on the ground are large(>500 mm) which are the on-axis optical systems,and the wide field of view and broad waveband become the most urgent problem to be solved.The catadioptric optical system with small aperture refractive corrector group was designed,which eliminated those aberrations brought by large relative aperture,wide field of view and broad waveband.The primary mirror was aspheric surface and easy to be fabricated.An example which optimized and evaluated with optical design software ZAMAX,and the practical result of observation for star were given finally.The aperture of this practical system was Ф750 mm,whose relative aperture was 1:1.32,the field of view was 4° and the waveband was from 500 nm to 800 nm,the practical capacity of detecting was above 15 Mv.The simple construction consists of several kinds of regular glass,and the imaging quality is very excellent. |
