Mathematical Formulation for Strain and Pressure Mapping Fiber Bragg Grating Sensors

Pandey N. K.,Tripathi Anupam

Abstract

In this paper, we report theoretical investigation of fiber Bragg strain and pressure mapping sensor with a novel mathematical formulation. A second order differential equation has been established showing relation between spatial periodicity along length of the fiber and effective refractive index of fiber core. Solution of this equation shows that magnitude of strain or pressure may be predicted from central wavelength shift of Bragg wavelength in the returned Bragg signal.
