设计了一种空间交会对接探测器光学系统。系统根据超焦距原理增大光学景深，通过像方远心光学结构，解决了变化物距下标志灯信号光在CCD成像面上成像质心不稳定的问题，应用改进的库克物镜结构有效地校正了对成像质心位置影响较大的垂轴像差。光学系统光学总长为36 mm，系统采用6片透镜元件，全部为球面结构，均为普通商用玻璃，避免了特种玻璃的使用。在800~880 nm波段，0.5~130 m物距下，系统的光学绝对畸变设计值优于±1 μm，视场角探测设计精度近似10″。设计的系统探测精度高，制造成本低，结构紧凑，适用于高精度空间飞行器交会对接领域。

An optical system for space rendezvous and docking simulator sensor is designed. The depth of field is increased by using the hyperfocal theory. The problem that the image centroid of signal light in CCD image plane changes with changing object distance is solved by adopting telecentric image space optical design. The lateral aberrations that affect the image centroid seriously is corrected by applying the ameliorative cooke optical configuration. The system has an optical length of 36 mm with 6 pieces of lenses, all of which are spherical surface with no special glass employed. For the 800~880 nm working wavelength and object length of 0.5~130 m, the design quantity of optical absolute distortion is less than ±1 μm with detected precision of field of view approximate to 10″. The designed system meets the requirement of high precision, low cost for manufacture and fine structure. It can be applied in the field of high precision aerocrafts space rendezvous and docking.
