Fiber Bragg Grating Force Sensing System with Temperature Compensation Scheme

Article Preview

Abstract:

Current study presented a simple, temperature-insensitive fiber Bragg grating (FBG) force sensing system. It is based on an optical intensity modulation scheme with a corrugated long-period fiber grating (CLPFG) filter. The temperature effect of signal variation is about 6%. Through FBG temperature compensating scheme the average temperature sensitivity is improved obviously (0.06 mV/°C).
