摘　　要：信标的亮度和尺寸直接影响波前传感器的最终精度,因此也影响了自适应光学系统对大气的矫正效果。给出了信标参数与自适应光学系统校正效果(斯特列尔比)之间的关系,考虑信标在运动目标中的应用,还给出了在自适应光学校正效果相同的情况下,人造信标与合作信标之间的等效性关系.The scale and brightness of the laser beacon play an important role in the ultimate accuracy of wave-front sensor and consequently determine the performance of the adaptive optics （AO） system. The relationship between the parameter of the laser beacon and the AO system performance, which is demonstrated through Strehl ratio, is discussed. Considering the application of laser beacon for the moving target, the equivalence between laser beacon and the cooperated beacon is presented.

关 键 词：信标参数 自适应光学系统 合作信标
