Multi-parameter fiber optic grating demodulator
We demonstrated in this work a filterless, multi-point and temperature-independent FBG (fiber Bragg grating) dynamical demodulator using pulse-width-modulation (PWM). In this approach, the FBG interrogation system is composed of a tunable laser and a demodulator that is designed to detect the. This interrogator is compatible with all specifications and models of OFSCN® FBG sensors (including Temperature, Stress, and Strain FBG sensors). It features adjustable port density (4, 8, 16, and 32 channels), high refresh rates (10, 20, 50, and 100 Hz). Fiber optic gratings are a new type of passive sensing element with high sensitivity, strong resistance to electromagnetic interference, corrosion resistance, and.
