Abstract

The roughness of sea surface affects the optical property of the exiting upward laser, which constrains the application of the LIDAR and Laser Communication in ocean. The paper designs one pool test to study the influence of sea-air interfaces and develops a corresponding geometric optical model. It analyzes the optical property of the upward laser through the sea-air interface systematic. Results show that the roughness of wavy sea surface will affect beam spreading, pointing and scintillation when transmitting through the boundary. Further, experiment results in one water tank with man-made wave show that the incident angle and divergence angle are very important to the upward laser on the real-time and statistics change. Selecting one appropriate incident angle and divergence angle will get one stabilized performance, which is useful to the laser practical application on the marine areas.
