Design & Analysis of Fiber Bragg Grating sensor package for hydro-acoustic application

Regina Mathias,Swarajit Pal,Dr J Deenathayalan

To improve protection and pressure sensitivity of grating, the Fiber Bragg Grating should be packaged. For polymer package, metal- tube package and side- hole package, simulation is done in Ansys [1-2]. For polymer package it is observed that as the Poisson’s ratio increases, the material strain also increases; the metal tube package covers the radial pressure, to increase its sensitivity; the side-hole package is designed non-symmetrically by structure. It is found that metal tube package shows more sensitivity than any other grating system followed by polymer packaged, and side-hole package analysis and simulation maintaining similar conditions.
