• Abstract: Applying remote sensing technology to surveying and mapping is the development trend of modern geological surveying and mapping technology. With the continuous improvement of optical load resolution, remote sensing surveying and mapping has become an important guarantee for social development and national economic development. Optical load determines the resolution, precision, volume and weight of the surveying and mapping space remote sensor, and is the core part of the remote sensor. In this paper, the structure form and optical properties of common space remote sensing surveying and mapping optical systems, such as high imaging quality transmission optical system, coaxial three reflectors optical system and off-axis three reflectors optical system, are introduced respectively, and the structure form and optical properties of new space reflective optical systems in the research and development stage are prospected. The analysis shows that according to different application environment and technical index, the reasonable selection of different kinds of optical system of remote sensing surveying and mapping can maximize the utilization of platform resources and meet the demand of remote sensing surveying and mapping. 将遥感技术应用到测绘当中是现代地质测绘技术的发展趋势，随着光学载荷分辨 率的不断提高，遥感测绘已经成为社会发展和国民经济发展的重要保障。光学 载荷决定了测绘空间遥感器的分辨率、测绘精度、卫星平台体积与重量，是遥 感器的核心部分。本文对高成像质量透射光学系统、同轴三反光学系统、离轴 三反系统等常用的空间遥感测绘光学系统的结构形式和光学性能分别进行了介 绍，并对处于研发阶段的新型空间反射光学系统的结构形式和光学性能进行了 展望。分析认为，根据不同的应用环境和技术指标，合理选用不同种类的遥感 测绘光学系统，可以最大程度利用平台资源，满足遥感测绘需求。
