Design and Implementation of an Underwater Optical Imaging System

Photograph and dynamic image recording of underwater objects are of great significance for military, geography, biology, offshore oil exploitation, port engineering and other fields. Traditional underwater imaging technology has become increasingly difficult to meet the needs of military and civilian. Compressed sensing will have a revolutionary impact on underwater imaging and underwater dynamic video recording. This paper describes the main components of the underwater compressed sensing optical imaging system: hardware and software algorithms. The subsystems such as the optical system and the system sampling components are described in detail. At the same time, the electronic control system of the system is discussed, and the performance parameters of each component are explained. Aiming at the special field of underwater imaging, the construction of algorithm system and the selection of reconstruction algorithm are described. The land experiment part of the underwater optical imaging system based on compressive sensing is realized by using POCS algorithm at room temperature in the laboratory, and the satisfactory image reconstruction effect is obtained.
