“高分二号”1m/4m光学遥感器由中国航天科技集团公司中国空间技术研究院北京空间机电研究所研制,首次采用天地一体化的系统设计方法,在体积和质量远小于传统设计的情况下,实现了我国当前在轨遥感相机的最高分辨率,使得我国民用遥感图像数据进入了亚米级时代。航天光学遥感相机的分辨率是一项关键指标,从遮光罩、相机镜头、焦面电路到地面处理中的任何一个环节都影响最终的成像质量。我国的空间光学遥感专业从20世纪60年代发展至今,一直延续着传统的 “High score on the 2nd ” 1m / 4m optical remote sensor by China Aerospace Science and Technology Corporation China Institute of Space Technology Beijing Institute of Space Electrical and Mechanical Development developed for the first time using the integration of the world system design method, the volume and quality is much smaller than the traditional design , The highest resolution of the current orbiting remote sensing camera in our country is achieved, which makes the civilian remote sensing image data of our country enter the sub-meter era. The resolution of aero-optical remote sensing cameras is a key indicator, affecting the final image quality from any aspect of the hood, camera lens, focal plane circuitry, and surface processing. China’s space optical remote sensing professional development from the 1960s to the present, has been the continuation of the traditional
