| 摘 要： | 在进行大气湍流强度、激光大气传输的研究时,大气相干长度是一个非常重要的参数.为了确定大气相干长度仪系统测量的A类不确定度,验证差分像运动法(DIMM)所测得的大气相干长度的可靠性,在相同传输路径上,分别运用差分像运动法和湍流积分法测量大气相干长度值.两种方法测量结果在量级和时间趋势上基本一致,两种方法得到相互验证.同时分析了两种测量方法得到的大气相干长度值存在差异可能的原因.大气相干长度仪的A类测量不确定度是通过贝塞尔法来计算的.通过实验可以得出,该大气相干长度仪系统的平均相对扩展测量不确定度小于20%.大气相干长度仪系统具备较高的可靠性,能够为大气光学传输的应用提供有价值的参考.

| Abstract: | Atmospheric coherence length is a very important parameter in the study of atmospheric turbulent intensity and laser propagation. To figure out the A-class measurement uncertainty of the atmospheric coherence measurement system, and confirm the reliability of the difference image motion method (DIMM), the atmospheric coherence length was measured by DIMM and turbulent integral method in the same propagation path. Results of both methods are similar in level and the time trend, so both methods can validate e... |
