Comparison of three technique of Brillouin lidar for remote sensing of the ocean

Three methods used to achieve Brillouin lidar in actual application are discussed. The scanning F–P interferometer technique cannot make real time measurement although it is high accurate. The edge technique has high sensitivity, but it requires extreme strict stable condition on environment. The technique combining F–P etalon and intensified CCD (ICCD) can stably work with few requirements on environment, and can make real time measurement. Therefore, the technique combining F–P etalon and ICCD will be the good choice for achieving Brillouin lidar practically.
