Abstract

The invention relates to a laser emission correction system and method for the structural deformation compensation of an optical machine. The system comprises a laser characteristic monitoring unit, an optical path unit, a laser and a control system; the light path unit comprises a spectroscope unit and a laser adjusting unit; one part of laser emitted by the laser device is emitted after passingthrough the spectroscope unit, the other part of the laser enters the laser characteristic monitoring unit; the laser characteristic monitoring unit determines the spot centroid position and spot sizeof the laser in real time; the control system compares the light spot centroid position and light spot size of the laser with initial set values; and the optical axis and position of the laser are adjusted in real time through the laser adjusting unit. Aiming at the problem that the convergence characteristic performance of a laser emission system is reduced due to the structural deformation of the optical machine, compensation is performed from two aspects of a beam divergence angle and an optical axis by detecting the state of the emitted laser in real time, so that the target arrival powerof the high-energy laser hitting a target is effectively improved, and the influence of factors such as temperature and external vibration on laser focusing characteristics is reduced.

Description

technical field [0001] The invention relates to the field of light beam control, in particular to a laser emission correction system and method for optical-mechanical structure deformation compensation. Background technique [0002] The damage efficiency of laser weapons is affected by factors such as laser energy and far-field spot characteristics. When the quality of the laser light source is constant, the far-field spot characteristics are mainly related to the convergence characteristics of the optical emission system, specifically expressed as the spot diameter and the position of the optical axis of the spot. Due to the complex optical path of the optical launch system of laser weapons, the optical-mechanical structure is easily affected by factors such as temperature, vibration, and stress release, resulting in deviations between the laser optical axis and the video tracking optical axis. On the other hand, the gap between the laser and the launch system The change of...
