Description

technical field [0001] The invention belongs to the field of optical detection, and relates to a detection system and a detection method of a space optical system, in particular to a detection system and a detection method for testing the detection limit and energy concentration of a space optical system. Background technique [0002] The space optical system detects space targets, and its detection ability determines the practicability of the system. In order to fully verify the detection capability of the optical system, a comprehensive test of its detection capability is required. The detection limit and energy concentration test are enough to evaluate the detection ability of the optical system comprehensively. On the one hand, detection limit testing can determine the limit response of the optical system to weak targets. On the other hand, the test of energy concentration can understand the energy distribution of the optical system after imaging the target. For space...
