Fiber Optic Sensor technology for Non-optical parameter measurement

Abstract — Use of traditional electronic sensors is limited in harsh, electromagnetic and high radio frequency environments which started interest in fiber optical sensing. Fiber optic sensors were developed by combining optoelectronic devices with fiber optic telecommunications systems. Optimization of components, cost reductions and recent researches gives fiber optic sensors with improvement in size, quality and performance. Commonly used fiber optic sensors are Intensity based, phase modulated and wavelength modulated fiber optic sensors. In this paper, an overview of fiber optic sensors, their working principle and non-optical parameter measurement applications are presented
