用于非完全校正自适应光学系统的人造导星

Laser guide star used in nonccmpletely correcting adaptive telescope

讨论了使用激光导星的非完全补偿自适应光学望远镜性能与导星亮度之间的关系,给出子孔径上剩余波前误差均方根值大于0.10λ,子孔径直径大于大气相关长度r_o时为产生瑞利导星和Na导星分别需要的激光能量.

The relationship between the perform ance of partial compensation adaptive telescope using laser guide star and the etar brightness is discussed. The laser energy requireme nts both for the Rayleigh guide star and the Na guide star are presented in case of the diameter of subaperture is larger than the coherence length γ0 and of the residual rms wavefront error over the eubaperture is larger than 0.10λ.
