Preliminary View of a Smart Technique for Materials Testing in the Laboratory using FBG Sensor

Abstract

Simple experiments for calibrating Fibre Bragg Grating (FBG) in order to measure strain and temperature have been successfully demonstrated in this study. This will allow convenient use of FBG sensor in the laboratory for measuring quantities. Linear curve fittings were employed for both the strain and temperature, and R 2 values are determined respectively. The result showed a perfect correlation between FBG, strain and temperature. The approach can be employed with ease, simplicity in an inexpensive manner, in order harness the advantages offered by FBG sensors such as accuracy, precision, speed and high resolution.
