Research on sensing characteristics of fiber Bragg grating F-P cavity

This paper mainly studies the Bragg F-P cavity sensing technology, studies the structure and sensing technology of the FP cavity installed in the F-P cavity, and discusses the possible impact of the introduction of the F-P cavity structure in the F-P cavity on the sensing technology. The report beer of grating structure and F-P cavity illustrates the necessity of parameter selection. The report beer of the integrated structure is calculated based on the optimized parameters, which illustrates the advantages of the integrated structure. The advantages of the integrated structure when the environment changes are further calculated. Spectra, the structure of the sensor was analyzed as well. The result is 1000nm/RIU.
