Paper Abstract

A differential demodulation technique capable of accommodating dynamic, high strain and high rate events is presented. The sensor system, based on a single fiber Bragg grating and a pulse modulated white light source, demodulates the first derivative of the strain signal. From model simulation, noise-limited resolution and dynamic range have been determined as functions of tunable system parameters.
