Blue-green Laser Fuse Underwater Target Detection

This thesis analyzes the optical character of the seawater firstly. Then it introduces the transparent windows of the blue and green laser in the seawater. It also discusses the possibility that the blue and green laser will be used in the torpedo fuse. Commencing from the principle, this paper explains the designing principle and method of the blue and green laser shooter. It analyzes the advertent items in the process of design and the method of driving, tuning, and protection measures of the laser shooter. Furthermore, it gives the principle diagram of the blue and green laser shooter used in the testing experiment.This paper also discusses the designing method and the designing project of the blue and green laser shooter. It introduces the testing components firstly and analyzes the characteristic of them. At last, it gives the principle program of the blue and green laser receiver used in the testing experiment. According to the principle program of the shooter and receiver, it gives a practical principle program for the integration of shooting and receiving machine.Combining with the possibility of researching the blue and green laser fuse discussed in the former content and aiming at the application in torpedo defense, the paper puts forward to the concept of communication system and defending system for torpedo green and blue laser fuse group. It explains the method for controlling mistakes in the system and the solutions for some important problems such as searching a target and self-cleaning the fuse channel of the laser.In conclusion, the main aim of this paper is trying to illustrate the importance and possibility of introducing the green and blue laser fuse to the field of ocean weapons. The concept of communication system and defending system for torpedo green and blue laser fuse group concerned in the article is just an embryo. There is still many details to be done.
