Abstract

The invention discloses a laser space synthesis transmission system based on an optical micro-scanning mechanism, comprising a transmission subsystem, a telescope subsystem, an imaging subsystem, anda spectroscope. In the system is used, spatial laser beams are output from a fiber laser and are input to a collimating assembly, wherein the negative lens group of the collimating assembly is mountedon an optical scanning mechanism, and the laser beams can be collimated by adjusting the optical scanning mechanism. The collimated laser beams are input into a transmission focusing component, and then are reflected to a fast steering mirror via the spectroscope, then enters a main mirror, a secondary mirror and a focusing component, and finally converge at the same position. The optical micro-scanning mechanism is a flexible hinge mechanism, has a micro-displacement function achieved by the driving of piezoelectric ceramic, has two-dimensional translation function, is driven by a piezoelectric ceramic stack, and has high motion resolution and a large stroke, and can achieve micron or sub-micron-order resolution and strokes of tens or hundreds of micrometers.

Description

technical field [0001] The invention belongs to the technical field of laser transmission, and in particular relates to a laser space synthesis transmission system based on an optical micro-scanning mechanism. Background technique [0002] The laser space synthesis transmission system is a system form that increases the power density of the target, and plays the role of converging multiple beams of laser energy or laser information to the target; at the same time, the transmission system includes a telescopic subsystem, which has the functions of long-distance target observation and The effect of compressing beam divergence. Laser space synthesis is to combine the laser beams with different spatial distributions through the transmission system to a high degree of convergence at the space target, which requires that the parallelism between the laser beams output by the laser is strictly consistent, so it is necessary to achieve sub-micron adjustment resolution of the laser be...
