Abstract

The physical phenomenon of the perturbation on the water surface caused by underwater acoustic signals has been analyzed in this paper. A laser probe detection system in laboratory with a semiconductor laser to measure signal underwater from the water surface was developed. Meanwhile, the synchronous measurement utilized a -200dB standard hydrophone was also done.The signal frequencies from 200Hz to 10KHz was measured and the results have been given. The experimental results show that the system is available.
