大气光学 大气传输 大气相干长度 斜程测量 atmospheric optics atmospheric transmission atmospheric coherence length bevel propagation path
摘要
介绍了一种斜程有限距离上大气相干长度的测量系统和方法,用系留气球搭载一个点光源,在地面用差分像运动测量法测量光波到达角起伏方差来确定实时的斜程大气相干长度值,与湍流廓线测量实验进行了对比,实验结果分析光学湍流廓线积分与相干长度仪测量二者的相关性较好.
Abstract
An instrument for the measurement of atmospheric coherence length is described. There is a light beacon on the captive balloon, atmospheric coherence length along bevel propagation path are measured via differential image motion measure angle-of-arrival fluctuation of optical wave. In addition, the profile observation results are used to check the results of the atmospheric coherence length measurement, and they are consisted quantitatively.
