摘要
使用单纵模355 nm激光作为发射光源,Fizeau干涉仪作为光谱鉴别设备,对条纹技术测风激光雷达进行了研究.对激光器频率抖动和Fizeau干涉仪光谱进行了分析,建立了条纹技术激光雷达系统,使用Fizeau干涉仪扫描的方法对系统进行了风速标定.利用研制的激光雷达系统对引入的参考光信号和大气后向散射信号进行同时测量,得到1.5 km以内的大气风速剖面.
Abstract
Using a single-model 355 nm laser as a transmitter and a Fizeau interferometer as a frequency discriminator,fringe-technique wind lidar were studied.Frequency jitter of the laser and spectrum of the Fizeau interferometer were analyzed,and a fringe-technique wind lidar system was constructed.The system was calibrated through scanning of the Fizeau interferometer’s spectrum.Using the developed lidar system,wind profile under the range of 1.5 km was obtained by the method of measuring the reference signal and the backscatter signal at the same time.
