摘要
研究了大气湍流情况下到达角起伏对激光外差探测系统干涉效率的影响。在实验室模拟大气湍流的条件下,分析检测了激光外差探测系统的干涉效率与信噪比,为提高激光外差探测系统的实用性能积累了一定的理论和实验数据。
The influences of atmospheric turbulence on interference efficiency due to the angle of arrival fluctuation in the laser heterodyne detection system were presented. The interference efficiency and signalto-noise ratio through turbulent atmosphere were detected and analyzed with a suit of laboratory turbulence generator. It provides theoretical basis and the experimental data for improving the property of the laser heterodyne detection system.
