Space optical communication transmitter, receiver, system and method

Abstract

The invention provides a space optical communication transmitting end, receiving end, system and method, the system comprises a transmitting end, the transmitting end comprises a microwave receiving module, a control module, a mark optical module, a beam combining module and a collimation scanning module, and the control module analyzes signal intensity information of microwave signals received bythe microwave receiving module and generates a control instruction; The marking light module generates a marking light signal, the data light signal and the marking light signal are mixed through thebeam combining module, and a laser signal is output; And the collimation scanning module collimates the laser signal output by the beam combining module, receives the control instruction of the control module and controls the output direction of the laser signal output by the collimation scanning module. Compared with a conventional space optical communication system, the space optical communication system is simpler in structure, the volume power consumption can be further reduced, and meanwhile, the space optical communication system has a continuous locking capability and can be more conveniently applied to mobile equipment.

Description

technical field [0001] The present disclosure relates to the field of space optical communication, in particular to a space light communication system and method for self-locking and self-tracking all-optical transparent transmission. Background technique [0002] Since the space optical communication technology was proposed in the 1930s, it has continuously attracted the attention of scholars in the field of communication at home and abroad. As a wireless communication technology, compared with microwave communication, space optical communication has the advantages of high bandwidth, good confidentiality and security, and does not occupy spectrum resources. It is expected to become the core technology in the future wireless communication field of human society. However, the existing space optical communication equipment requires extremely high alignment accuracy. Conventional transmitters and receivers have only a very small window angle. The structure is complex and the v...
