摘　　要：为了满足空间交汇对接飞行器姿态精确测量的要求,设计了一种中短距离使用的宽视场远心对接成像敏感器光学系统。该对接成像敏感器光学系统焦距f=10mm,成像范围为1.5~30m,视场角为54°,光谱范围为430~680nm,工作温度范围为-40^+40℃。为满足系统成像范围的要求,利用景深公式计算了不同入瞳直径和对准距离时的成像范围,给出了易于设计、检测和保证入瞳最大化的参数设计方案,并进行了光学系统设计和消热差设计。像质分析结果表明,设计结果在使用温度范围内均能满足像质要求,结构简单,易于加工装配。In order to meet the requirements of accurate measurement of spacecraft＇s attitude for rendezvous and docking, a wide field telecentric optical system of docking imaging sensor used for middle-short distance is designed. For the design docking imaging optical system, the focal length is 10 mm, imaging range is 1. 5-30m, Field of view is 54°, wavelength range is 430-680nm, operating temperature range is -40-40℃. To meet the system requirements of the imaging range, the imaging range with different entrance pupil diameters and aiming positions is calculated using the formula of depth of focus, parameters solution with easily design, test and maximize diameter is given , the optical system is designed and athermallized. The imaging analysis results show that the design is a feasible scheme with operating temperature range, and the structure is simple, the fabrication is easy.
