摘要
在同轴三反射光学系统基础上,采用视场离轴方式,设计了一个在地球同步轨道上对地观测的空间离轴三反射光学系统.该系统同时具有大线视场和大相对口径的特点,设计结果表明,成像质量达到了衍射极限.
Based on the coaxial three-reflective system, a space off-axial three-reflective system applied to observe the earth on the geostationary orbit was designed by means of field of view off-axis form. The characteristics of the system are both large linear field of view and large relative aperture. The results of design indicate that the quality of imaging is so high as to have arrived at the diffraction-limitation.
