Abstract

The invention discloses a light beam precision pointing device based on a resolution multiplied compliant mechanism, comprising a mirror bracket component, a driving mechanism and a control mechanism. The mirror bracket component is connected with the driving mechanism through the resolution multiplied compliant mechanism, the resolution multiplied compliant mechanism comprises a base and a flexible hinge fixed on the base and the mirror bracket component is fixed at the top of the flexible hinge; the driving mechanism comprises two drive motors used for pushing the flexible hinge and fixed on the base and the two drive motors are symmetrically arranged at two sides of the lower part of the flexible hinge. The invention has the advantages of compact structure, convenient processing, simple assembling, no friction loss, no movement clearance, no need for lubrication, high locating precision, network control, simple and convenient use, high reliability, strong adaptability and wide application range.

Description

technical field [0001] The invention relates to the field of laser communication, in particular to a beam precision pointing device based on a resolution multiplying compliance mechanism. Background technique [0002] The wireless optical communication system is also called "free space optical" communication system, which uses light beams (such as lasers) as optical communication signals, without laying transmission cables or optical cables between terminals, and data or information is coded and modulated into a beam with a wide divergence angle. On a small narrow beam, it is then transmitted through free space from the transmitter to the receiver, and the receiver mediates the received beam to obtain raw data or information. The working principle of the wireless optical communication system itself ensures that the system has high data security and confidentiality, but requires that the transmitter and receiver of the narrow beam must be aligned with each other, the mechanic...
