The Test System of DFB Fiber Laser Hydrophone Acoustic Pressure Sensitivity

Acoustic pressure sensitivity is an important indicator of hydrophone. This paper introduced the composition of the test system of DFB fiber laser hydrophone acoustic pressure sensitivity, detailed explanation of every steps, highlighted matters needed attention in the testing process, illustrated the usage of main equipment involved, and finally gave method for generating frequency response curve of the hydrophone. In testing of hydrophone, the system has a certain degree of versatility and practicality.
