Comparative Accuracies of Fiber Bragg Grating Sensing Systems for Temperature Measurement

Abstract

In this study, using state-of-the-art optical simulation software, we design, simulate and quantify the comparative accuracies of two types of FBG-based optical sensing systems: one is designed for lengthy, multiplexed multi-temperature measurements, the other for single-point measurements. Results and discussion are made to analyze the comparative performances, particularly in terms of linearity and accuracy.
