Paper Abstract

A new method is presented to interrogate the reflected wavelength shift of in-fiber Bragg grating used as sensors. The system can locate the center of the reflected wavelength of in-fiber Bragg grating with high precision and erase the influence of non- linearity and hysteresis of pzt from the measurement data effectively.
