Development Status of High Energy Laser Protection Technology for Satellites
The continuous development of high-energy laser technology has gradually become a practical threat to the safety of satellites in orbit.This article introduces the research progress on the damage mechanism of high-energy laser weapons on satellites,and clarifies the damage mechanisms of high-energy continuous laser and pulse laser.And based on the protection characteristics of optical systems such as satellite solar cell arrays,cameras,star sensors,as well as non-optical key structures such as thermal control multilayer and composite propellant storage tanks,the main principles,development status,and technical characteristics of various high-energy laser protection technologies such as linear optical protection films,non-linear optical protection films,phase change materials,mechanical shutters,high damage threshold films,and protective cov-ers were summarized and analyzed.
