Abstract

A model has been constructed for determining the effect of instrumental and calibration errors on the accuracy of a method for strain−temperature discrimination using polarization-Brillouin reflectometry based on measuring the Brillouin frequency shift in two polarization axes of an optical fiber. It is shown that the errors caused by the discrepancy of the calibration coefficients are negligible. The optimal hardware requirements for the reflectometer are determined. The experimental results of spectral scanning at the maximum resolution attainable in this study are in agreement with the results of computer simulation.

偏振-布里渊反射法同时测量各向异性光纤中温度和应变的精度的理论和实验估计

摘要

已经建立了一个模型，用于确定仪器和校准误差对基于偏振-布里渊反射法的应变温度判别方法的准确性的影响，该方法基于测量光纤在两个偏振轴上的布里渊频率偏移。结果表明，由校准系数差异引起的误差可以忽略不计。确定反射仪的最佳硬件要求。在这项研究中可以达到的最大分辨率的光谱扫描的实验结果与计算机模拟的结果一致。
