Space Debris Removal System Based on Split Multi-telescope Form of Laser Beam Combination

Abstract

The space debris removal system based on the form of separate multi-telescope laser combining beams involves the field of space technology. It solves the problems of thermal deformation of the components in the optical path in the process of the existing ground high-energy laser emission system for space debris. This system emits multiple beams from the ground. The power laser is directed to the space debris, and the superposition of multi-beam energy realizes the ablation effect on the space debris. In order to improve the effect of the light beam on space debris, the system uses adaptive optics technology to correct the thermal deformation of optical components and the disturbance caused by the atmosphere; at the same time, the system uses laser guide star technology to improve the ability to act on faint space targets . The space debris removal system is a way to remove space debris on the surface of the earth. The system applies the principle of energy superposition and adopts multi-beam laser emission, which can realize the processing of space debris at different orbital heights. The key unit technology realizes The difficulty is reduced, the maintenance is convenient, and the cost is also reduced accordingly.

Description

technical field [0001] The invention relates to the field of space technology, in particular to the technology of removing space debris. Background technique [0002] Space debris refers to man-made objects orbiting around the center of the earth, which generally have no use value. It is the product of human space activities, including stopped spacecraft (such as satellites, space stations, space shuttles, etc.), rocket residues used to launch satellites, debris produced by the separation of multi-stage rockets, and collisions between space objects. fragments etc. With the progress of human space activities, the number of space debris presents a growing trend, and its potential collision risk seriously threatens the safe operation of spacecraft in orbit. [0003] Research on space debris focuses on monitoring and removal. To monitor space debris is to give its position and changes in the sky at every moment, and determine its orbit. Although for some regular space debris...
