摘要

Recent work conducted on developing a fiber tip based Fabry-Perot (FTFP) sensor system for acoustic measurements is presented in this article. It has been determined that this system can be used to detect acoustic fields in the frequency range of 50 Hz to 7.5 kHz with an optical phase sensitivity of 0.9 rad/Pa. A series of experiments is performed to investigate the possibility and potential use of this sensor system, which is designed to be implemented in a multiplexed architecture for providing response measurements to a structural acoustic control system.
