Abstract
To improve measurement accuracy of spectrally distorted fiber Bragg grating temperature sensors, reflection profiles were curve fitted to Gaussian shapes, of which center positions were transformed into temperature information.
By applying the Gaussian curve-fitting algorithm in a tunable bandpass filter demodulation scheme,
