A Novel Method of Edge Filter Linear Demodulation Using Long Period Grating in Fiber Sensor System
A novel method of linear demodulation based on edge filter is presented. An experimental system is built up in which LPG is used as the edge filter. We achieve linear demodulation with a bandwidth of 5nm.
