研究目的
To propose and demonstrate a fiber-optic sensor for simultaneous measurement of temperature and pressure using FP and AR mechanisms in a SMF-HCF-SMF structure.
研究成果
The proposed sensor can measure temperature and pressure simultaneously due to the different sensitivities to temperature and pressure of AR mechanisms occurring in the silica cladding of the HCF and FP interference occurring in the hollow core. The sensor has advantages of small size, simple and robust structure, and dependability, showing great potential for highly sensitive gas pressure and temperature measurements in harsh environments and industrial applications.
研究不足
The technical and application constraints of the experiments, as well as potential areas for optimization, are not explicitly mentioned in the paper.
1：Experimental Design and Method Selection:
The sensor is constructed from a segment of silica HCF sandwiched by two segments of SMFs, with one joint offset spliced to make a gas tunnel.
2：Sample Selection and Data Sources:
The inner and outer diameters of the HCF used in the experiment were 100 μm and 165 μm, respectively, with a ring cladding thickness of
3：5 μm. List of Experimental Equipment and Materials:
A broadband light source (BBS, FiberLake ASE), an optical circulator (OC), an optical spectrometer analyzer (OSA, YOKOGAWA AQ6370C, Japan), and an oven (SIOM SG-XL1200, China) were used.
4：Experimental Procedures and Operational Workflow:
The reflection spectra of the sensor changing with temperature and pressure were measured.
5：Data Analysis Methods:
The spectral envelope of the sensor was extracted by the software Origin, and linear fitting was used to determine the temperature and pressure sensitivities.
