Optical system design of a two-linear array stereoscopic mapping CCD camera

In order to obtain the image of 7 m resolution with the Chang'E-2 CCD stereoscopic camera on the 100-km-altitude circular orbit, a two-linear array CCD camera stereoscopic mapping optical system is designed. The principle of two-linear array stereo mapping camera is described. According to the satellite requirements, the main parameters of the optical system are calculated detailedly. The focal length of the system is 144.4 mm, the view angle is 42'E-2 satellite CCD stereoscopic camera are obtained. The images are clear and rich of detail information, demonstrating the effectiveness of the optical system
