摘要： 针对自适应光学系统将要探测的空间非自发光目标，进行了光谱特性和星等估计的研究；研究了空间非自发光目标反射太阳光穿过大气层而进入自适应光学系统的波前探测器的子孔径内的光子速率；同时还针对反射太阳光的空间目标亮度太低，研究了激光照射目标后的相应情况。

Abstract: In this paper researched the ground spectrum characteristics and star magnitude of spacial non-self-illumination object which is probed by Adaptive Optics System (AOS). The non-self-illumination object reflects sunlight into wavefront sensor system of AOS through atomsphere. The photon speed entering AOS's subaperture is also evaluated. In the contrast, compared the differences between sunlight-reflecting object and laser-illuminated object.
