Design of Optical Fiber Fabry-Perot Sensors Based on Intensity and Phase with Parallel Processing

ABSTRACT

For fiber Fabry-Perot sensor vulnerable to external parameters such as electromagnetic, noise and displacement impact, reducing the problem resilience, research and design new fiber Fabry-Perot sensor with parallel processing capabilities based on the intensity and phase of perception. First, according to various types of external parameters and the degree of interference, established the intensity and phase-oriented demodulation algorithm then gives a fiber Fabry-Perot microcavity sensor performance analysis model is then proposed for the fiber Fabry-Perot sensor has a solution parallel processing algorithms tune transformation, and finally developed a fiber Fabry-Perot sensor has strong adaptability and measurement effects. Experimental results show that the single phase demodulation and intensity demodulation fiber Fabry-Perot sensor design compared to the proposed sensor design has obvious advantages in accuracy and performance of the strain.
