Laser beam-combined space debris scavenging system based on self-adaptive optical technology

Abstract

A laser beam-combined space debris scavenging system based on the self-adaptive optical technology, relates to the field of space technology, aims to solve the problem that elements in the light path are easy to deform when heated in the process that the space debris is scavenged by the conventional ground high energy laser emitting system. According to the invention, multiple high power laser beams are emitted to the space debris from the ground surface to realize ablation effect on space debris through the stacking of the energies of the multiple beams; in order to improve the action effect of the laser beams on the space debris, the self-adaptive optical technology is adopted in the system for correction of thermal deformation of the optical elements and disturbance caused by atmosphere; and meanwhile, the laser guide star technology is used by the system, so as to improve the capacity of the action on dark weak space targets; the space debris scavenging system is a way, by which space debris scavenging on earth surface is realized, that space debris with different orbit altitudes are scavenged is realized with the utilization of the principle of energy stacking and the adoption of multiple laser beams for emission, the technical realization difficulty of every key unit is decreased, the maintenance is convenient, and the cost is correspondingly reduced.

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...
