Abstract

Measurements were carried out using finite impulse response (FIR) filters. The objective was to improve the wavelength detection accuracy in fiber Bragg grating (FBG) sensors. The test the effectiveness of the FIR filter, the noise generated was deliberately made large by cutting the fiber in the reflected wave in such a way that the reflected wave from the cut end experiences similar optical path length as traveled by the signal wave to generate observable interferometric noise. For a number of strain values from 0-1000 με applied to the FBG, the maximum error strain in measurement was found to be ±14 με.
