摘要

为了实现对14等星目标的精确探测，本文设计了一个大视场的探测光学系统。首先，根据选定的CCD231-84 E2V光电探测器计算了系统入瞳和焦距等初始参数，依据选定的参数进行了初始结构的选型，选定了马克苏托夫望远镜的形式并对其进行了改进。然后，对设计结果进行了探测性能分析。最后，对设计好的系统进行了公差分析及优化，使它能满足加工装配需求。设计与分析结果表明：该探测光学系统折反射镜全表面采用球面，系统总长350 mm，全视场30 μm包围能量分布均在86%以上，最大畸变小于1%。该系统视场大、结构紧凑、装调难度低、探测灵敏度高、探测范围广，可用于目标的精确探测。

Abstract

To achieve the accurate detection of 14th-magnitude targets， a large-field-of-view optical detection system was designed. First， according to the selected CCD231-84 E2V photodetector， the initial parameters， such as system entrance pupil and focal length， were calculated. Then， based on the selected parameters， the initial structure was selected， and the form of the Maxutov telescope was selected and improved. Then， the detection performance of the design results was analyzed. Finally， a tolerance analysis and optimization of the designed system were conducted so that it could meet the needs of processing and assembly. The design and analysis results indicate that the optical detection system adopts a spherical catadioptric mirror surface， the total length of the system is 350 mm， the full field of view for a 30 μm surrounding energy distribution is >86%， and the maximum distortion is <1%. The system has a large field of view， aperture， and relative aperture. It is compact and of suitable size， easy to install， and offers high detection performance， high detection sensitivity， and a wide detection range， making it useful for the accurate detection of targets.
