Laser follow-up device and method based on adaptive coupling system

Abstract

The invention provides a laser follow-up device and method based on an adaptive coupling system, and the method comprises the steps: observing a plurality of target points and laser drop points through a telescope system, comparing the light intensity changes of the target points and the laser drop points, and judging whether the laser drop points are located at the corresponding target points or not; the coarse tracking system adopts a coarse tracking algorithm to scan a target and tracks the target according to a scanning result, so that the target is located in the center of a field of view; the fine tracking system adopts a fine tracking algorithm to detect target information and adjusts a target tracking angle according to the target information; the optical fiber coupling system adopts an optical fiber coupling algorithm to carry out self-adaptive adjustment on multiple beams of laser, so that a laser drop point corresponds to a target point, and an aiming angle is obtained; and the control system is used for performing data transmission, driving transmission and motor control, and controlling the laser to perform same-light-path reverse laser emission according to the aiming angle. According to the invention, high-precision tracking of a plurality of moving targets can be synchronously realized, and the remote laser energy transfer efficiency is greatly improved.
