Research progress on high-resolution imaging system for optical remote sensing in aerospace

With the continuous development of optical imaging technology and the growing demand for re-mote sensing applications, cross-scale high-resolution optical technology has been widely used in the field of remote sensing. In order to obtain more detailed information on the target, domestic and foreign researchers have carried out relevant research in different technical directions. In this paper, through the technical classi-fication of remote sensing imaging, we introduce a representative aerospace optical remote sensing high -res-olution imaging system. It focuses on monomer structure, block expandable imaging, optical interference synthesis aperture imaging, diffraction main mirror imaging, optical synthetic aperture and other technolo-gies. It provides a new idea for the development of high-resolution optical remote sensing loads on the ground.
