| 英文摘要 | In this paper, a pressure-gradient fiber laser hydrophone is demonstrated. two brass diaphragms are installed at the end of a metal cylinder as sensing elements. a distributed feedback fiber laser, fixed at the center of the two diaphragms, is elongated or shortened due to the acoustic wave. there are two orifices at the middle of the cylinder. so this structure can work as a pressure-gradient microphone in the acoustic field. furthermore, the hydrostatic pressure is self-compensated and an ultra-thin dimension is achieved. theoretical analysis is given based on the electro-acoustic theory. field trials are carried out to test the performance of the hydrophone. a sensitivity of 100 nm mpa(-1) has been achieved. due to the small dimensions, no directivity is found in the test. |
