Abstract


Laser underwater target detection technology is a development of advanced detection technology , which combines laser technology , communication technology , signal processing and recognition and electronic technology is one , and has broad application prospects . Of the research and development of technology , both in theory and practical application has a very important value . At present , Europe and the United States and other developed countries have established their own underwater the photoelectric detection research system , and has been used in military and civilian fields . The paper first discusses the current underwater vision methods and applications , and laser-based technology , underwater imaging method and characteristics , and further analysis of the main technical characteristics of the muddy water underwater imaging . In the study of the laser underwater transmission characteristics based on coaxial synchronous scanning method and laser flying spot beam expander synchronous scanning system designed to reduce the one-way and multi -way scattered light . Flying spot scanning system using synchronous scanning one way to reduce the laser scattering , the angle between the laser transmitter and receiver window , with the total reflection method to reduce the laser close- range scattering . The experiments show that the system has a good dissipated shot effect , to achieve the expected design goals . In conclusion, the article discusses the laser imaging method deficiencies and Prospects .
