| 摘 要： | 对基于瑞利激光导星的大气湍流廓线测量系统进行了研究,系统利用脉冲激光在测量区域大气层内不同高度形成信标星,以此测量地面至信标星之间的大气湍流信息。本文在分析瑞利激光导星湍流廓线测试的原理和系统组成基础上,对系统关键参数进行了优化选取,并设计了激光发射系统和差分像移接收系统,最后对系统性能进行评估。结果表明:系统可对地面高度0.2~10 km范围内的大气进行湍流廓线测量,该技术在地基天文观测、星地激光通信、地基激光武器领域具有重要的应用价值。

| Abstract: | Atmospheric turbulence profile test system based on Rayleigh laser guide star is studied,the pulsed laser used to form beacon star at different heights in atmospheric,then the atmospheric information between ground and guide star were obtained.Based on the analysis of principles and system components,the system critical parameters were optimized.And the laser transmits system and differential image motion system was designed.Finally,the system performance,the results showed that 0.2~10 km atmospheric turbulence profile can be measured by this instruments.This can be used in the area of astronomical observations,satellite-ground laser communications,and ground-based laser weapons. |
