Two Main Factors That Limit Application of Temperature Optical Fiber Sensors

In this paper,temperature optical fiber sensors are analyzed.Based on our long-time experiment,the reasons that limit utilization of most optical fiber sensors are analyzed and several improvable methods and suggestions are given.We conclude the important causes that limit application of optical fiber sensors are long-term stability and reliability,two main factors that influence stability and reliability are drift of light source power and aging of optical fibers protective coating,especially the aging of optical components lie in detected areas.
