Paper Abstract

A new designed sapphire fiber-optic sensor, aiming to improve the performance of the traditional sapphire fiber- optic sensors for high temperature measurement, is provided in this paper, in this system, an additional U-shaped sapphire fiber is used together with a modulated LED reference signal. It has advantages of both high sensibility of the single-band type and the high stability of the dual- band system. It is a good method to improve the stability of the traditional radiation based sapphire fiber-optic sensor without sacrificing high sensibility.
