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.
