星敏感器是一种姿态测量系统，用于测量飞行器的实时姿态。该系统是一种基于CCD探测器的适用于星敏感器的光学系统。通过相关参数的计算，利用ZEMAX平台实现了具有良好成像质量的光学系统结构设计。该系统焦距为50 mm，F数为1.8，具有较大的视场角：2=23°，光谱范围较宽：500~850 nm，中心波长为680 nm。捕获三颗导航星的概率达100%。满足星敏感器对弥散斑、能量集中度和畸变等特殊要求。倍率色差得到了很好的校正，仅为0.087μm。系统仅使用6片球面透镜，结构简单紧凑，易于加工制造。

Star sensor is a kind of attitude measurement system, which is used to measure the real- time posture of the aircraft. A new kind of optical system of star sensor based on CCD was designed. And the calculation of relevant parameters was carried out. This kind of optical system with wide field of view, wide spectra range and good imaging quality was realized in ZEMAX software. This optical system has an effective focal length of 50 mm, an F- number of 1.8, a field of view of 23 degrees, a spectral range of 500- 850 nm and a primary wavelength of 680 nm. The capture probability of three navigation stars is up to 100%. The especial requirements of the spot, encircled energy, distortion etc. are all satisfied. Lateral color is corrected greatly. The value is 0.087μm .The system only contains 6 pieces of lens. The structure is not only simple and compact, but also easy to manufacture.
