Abstract
A novel design of an underwater acoustical pressure transducer based on a Fiber Bragg Grating is presented. In this transducer the sensing grating is writen in a rare-earth doped fiber and operates as an optically pumped Distributed Feedback (DFB) laser. Presented sensor has higher resolution, compared to a sensor using a passive Fiber Bragg Grating. A profiled membrane is used in the transducer to achieve equalization of stress acting on the grating along its length. Results of Finite Element modeling of the transducer are presented.
