摘要：

Based on the special chromatic aberration and thermal aberration of diffractive optical element, which are used in optical system of visible camera for space debris, a novel compact and good image quality large relative aperture space debris camera optical system was designed. The novel system solved the problem that the conventional system had small relative aperture and complex structure. The novel system had an effective focal length of 100 mm, a relative aperture of F/1.5, a field of view of 6°. The system met the requirements of visible space debris camera in encirc energy, the dispersion spot diameter, lateral color, distortion, athermalization and so on. This novel system had light weight, compact structure and good image quality by using diffractive optical element, which provided a new idea for designing visible space debris camera optical system.
