摘要
根据传统的矩阵光学原理建立理论模型,研究了高双折射光纤环镜的滤波特性,分析了高双折射光纤环镜滤波器的解调原理。经传感检测验证,该解调系统对温度的分辨率为0.05℃,线性度达到0.9986,实验结果与理论分析相吻合,显示了该系统具有良好的稳定性,且结构简单、精确度高、价格低廉、使用方便。
In the paper,theoretical model was established,the characteristic of the High Birefringence Fiber loop mirror＇s filter was studied and the principle of High Birefringence Fiber loop rein＇or filter＇s demodulation was analyzed according to the principle of the traditional matrix optics.The temperature resolution to this demodulation system is 0.05 ℃and the linearity reaches 0.9986 after the examination and confirmation of the sensor.The experimental result and the theoretical analysis demonstrate this system has a good stability and simple structure with high precision,low price and convenient use.
