英文摘要	3-D remote sensing based on the combination of ladar and 2-D remote sensing data is one of the most important emerging trends in the field of remote sensing. We design a co-aperture optical system to be used for 3-D remote sensing payload. In order to use the spatial limitation of the satellite as input conditions, we modify the initial equation of the three-mirror system. The original parameters are determined from the solution of the modified equation and then a coaxial three-mirror system is designed. The fields are biased to avoid secondary obstruction caused by the image plane. The focal length and F number of the system are 2 400 mm and 5.33, respectively. The tertiary mirror is placed in front of the primary mirror to shorten the on-axial length by using three plane mirrors, which resolves the contradiction between long focal length and spatial size. The system is free of chromatic aberration, has small distortion and offers a good performance. The modulation transfer function approaches the diffraction limit, and the system has a large relative aperture, of which the geometric encircled energy is confined within a circle of diameter 35 m. The designed optical system provides good performance with high resolution and satisfies the requirements for ladar. 2018, Science Press. All right reserved.
