基于标尺效应的级联光纤F-P微腔温度传感器及其制备方法
摘要：
本发明提出一种基于标尺效应的级联光纤F-P微腔温度传感器及其制备方法。该温度传感器包括一根单模光纤和在其内部的第一反射镜、第二反射镜、第三反射镜，所述第一反射镜和所述第二反射镜形成第一F-P微腔，所述第二反射镜和所述第三反射镜形成第二F-P微腔；一种基于标尺效应的级联光纤F-P微腔温度传感器的制备方法，通过计算机控制，采用飞秒脉冲激光微加工技术，用于制备该温度传感器。本传感器通过标尺效应提高了干涉条纹的对比度，而且同时增大了干涉条纹的自由光谱范围，从而实现高分辨率和大范围的温度测量，并改进工艺以实现低损耗和高性能传感特性，这将在大型系统故障监控和健康监测等领域有广泛的应用前景。
摘要（英）：

The invention provides a cascaded optical fiber F-P micro-cavity temperature sensor based on a scale effect and a manufacturing method thereof. The temperature sensor comprises a single-mode optical fiber, a first reflecting mirror, a second reflecting mirror and a third reflecting mirror arranged inside the single-mode optical fiber, wherein a first F-P micro-cavity is formed by the first reflecting mirror and the second reflecting mirror; and a second F-P micro-cavity is formed by the second reflecting mirror and the third reflecting mirror. In the manufacturing method of the cascaded optical fiber F-P micro-cavity temperature sensor based on the scale effect, the temperature sensor is manufactured by adopting a femtosecond pulse laser micro-processing technology under the control of a computer. In the sensor, the contrast of interference fringes is increased through the scale effect, and the free spectrum range of the interference fringes is enlarged simultaneously, so that high-resolution and large-range temperature measurement is realized; a process is improved to realize low-consumption and high-performance sensing characteristics; and the temperature sensor has wide application prospects in the fields of large-sized system fault monitoring, health monitoring and the like.
