摘要

本文报道了光纤包层直径对倾斜光纤布拉格光栅辅助折射仪精度和分辨率影响的研究结果。倾斜光纤布拉格光栅是用于环境监测的高精度光纤传感器的基本元件。采用光谱包络分析的综合处理算法进行了对比研究。结果表明，光纤包层直径越小，传感器精度越低。同时，直径的增加会降低光谱模式的对比度，从而阻碍了高效传感器元件的发展。

Correlation between optical fibre diameter and characteristics of tilted fibre Bragg grating-assisted sensors

We report the results of a study on the influence of the fibre cladding diameter on the accuracy and resolution of tilted fibre Bragg grating-assisted refractometers. Tilted fibre Bragg gratings are an essential element used to develop high-precision fibre sensors for environmental monitoring. Comparative research was performed using one of comprehensive processing algorithms employing spectral envelope analysis. It was shown that the sensor accuracy decreases with decreasign fibre cladding diameter. At the same time, an increase in the diameter deteriorates the spectral pattern contrast, thus impeding the development of high-efficiency sensor elements.
