Abstract :
Summary form only given. We experimentally demonstrated a tilted fibre Bragg grating (FBG) demodulator that has a simple and compact scheme. Using this, wavelength-encoded information from a dual head strain sensor is demodulated with high stability and accuracy, independent of temperature perturbation at both sensor and demodulator FBG.
