  • The design method of the common single-mode all-fiber (SMF) hydrophone and its drive circuit is provided. During the process of the design, SMF whose transmission wavelength is 1550nm was chosen,the MQW-DFB(multiquantum well distributed feed back)semiconductor laser was taken as the light source, MAX3263 and MAX038 were selected to design the laser driver and high-performance sine-wave signal generator, respectively, and InGaAs PIN was taken as the optoelectronic detector. The experiments indicate that the sensitivity of the fiber hydrophone presented in this paper is higher than that of the standard hydrophone (piezoelectricity type) by 50dB~60dB(1kHz~30kHz).
