摘要
文章阐述了星载大视场多光谱高分辨率CCD相机光学系统的设计过程 ,并给出了设计结果。该系统采用像方远心光路与多光谱棱镜分光型式 ,4个谱段在整个视场的调制传递函数在Nyquist频率 77lp/mm处均接近衍射极限 ,满足了色漂移、多光谱光学配准、偏振、光学热补偿等工程要求。
The Paper Introduces the optical system design of wide-field, multi-spectral and high-resolution CCD camera and gives the result This system adopts telecentric system and uses prism as spliter The MTF value of each spectrum is close to the diffraction limit at Nyquist frequency of 77lp/mm The result is satisfied to the requirements of color-excursion?multi-spectral registration?polarization and athermalisation
