Research progress of scattering lidar technology for ocean profile detection

Effective detection of ocean material profile distribution plays a vital role in marine biological research, protecting ocean ecological environment and resource utilization. Compared with other detection technologies, lidar has the advantages of all-weather, high temporal-spatial resolution and rapid and efficient access to its vertical distribution information. Lidar is one of the important means to detect the environmental parameters of ocean profile. Firstly, the basic working principle of lidar system is introduced, the characteristics of Raman lidar, Brillouin scattering lidar and fluorescence detection lidar are reviewed. Then the existing problems of lidar technology in detecting the vertical distribution of marine materials are discussed, finally, the development trend of this technology is prospected.
