The invention belongs to the technical field of space optics, and specifically relates to a multipurpose optical antenna system for laser communication; it includes a telescopic unit 1, a lens assembly 2 and a beam splitting assembly 3, and when the function of an optical antenna for laser communication needs to be realized, the lens assembly 2 passes through the The main mirror room back plate 13 extends into the middle of the main mirror 11, is positioned through the lens assembly positioning pin hole 134 and is bolted to the main mirror room back plate 13 through the lens assembly mounting screw hole 133; When the light pipe is functioning, the beam splitting assembly 3 is positioned through the beam splitting assembly positioning pin hole 136 and bolted to the main mirror chamber back plate 13 through the beam splitting assembly mounting screw hole 135; the system can be replaced by the optical assembly on the main mirror chamber back plate Realize the switching between the functions of the laser communication optical antenna and the self-collimating collimator, avoiding the additional workload and cost of developing the collimator separately.
Description
technical field [0001] The invention belongs to the technical field of space optics, and in particular relates to a multipurpose laser communication optical antenna system. Background technique [0002] With the continuous improvement of space optical remote sensor indicators, the requirements for data transmission rate are also getting higher and higher. Due to the advantages of high transmission rate and good confidentiality in space laser communication, this technology has become one of the hotspots in the field of space optics. [0003] The laser communication optical transceiver needs to be installed on a dynamic target for joint debugging with the system. The self-collimating collimator used in traditional static working conditions cannot meet the technical requirements of multiple disassembly, multi-angle, and multi-working conditions in system debugging (refer to Literature: Gao Minghui, Li Lifu, Xu Jingli, Bao Jinhe. Design of a new multi-band large-aperture collim...
