Matching design of separated vision measurement system between receiving system and transmitting system based on cooperative target

The separation of transmitting and receiving means that the optical axes of the receiving and transmitting optical systems are not coaxial. It has the advantages of simple installation and adjustment, no stray light interference in the shared optical path, etc., which can effectively reduce the measurement error. Combined with the application of cooperative target, the relative measurement accuracy between two spacecraft can be effectively improved. In this paper, a design scheme of separated vision measurement system between receiving system and transmitting system based on cooperative target is proposed. Through the analysis of entrance pupil constraint, diffuse influence and imaging optical path, the structural layout of cooperative target and the parameters of visual measurement sensor are reasonably designed, so that the light spot reflected by cooperative target can be imaged completely and clearly in the receiving optical system.
