摘要：如今，传感器在朝着微型、精密、智能等方向发展。光纤传感器具有电绝缘、精度高、微结构等特点成为人们研究的热点。本文根据光纤干涉仪传感器的原理与其在实际中的一些运用，制作设计了将微管熔接在Michelson光纤干涉仪的反射端的新型结构，主要研究如下：
首先，本文具体分析了Michelson干涉仪的发展历程及其研究现状和未来的发展情况，在与其他干涉仪的对比和一些实际运用中发现了光纤Michelson干涉仪传感器的一些不足的地方。其次，目前大部分的光纤传感器制作工艺复杂、成本高不利于光纤传感器的普及，且大多数的光纤Michelson干涉仪传感器的末端暴露于空气中，容易受到外部环境的干扰。因此，本文结合前人的一些研究和对光纤Michelson干涉仪的一些了解，设计了在光纤反射端面熔接二氧化硅微管结构的新型光纤Michelson干涉仪传感器。另外，描述了常见的几种光纤干涉仪传感器，描述了Michelson干涉仪的一些基本特性。此外，详细的介绍了新型端面反射光纤Michelson干涉仪传感器的设计与制作过程。最后，通过实验的方法探究其对于温度与折射率响应情况，并计算出其温度与折射率的响应灵敏度。

Research on Refractive Index and Temperature Sensing Characteristics Based on Fiber Michelson Interferometer
Abstract:Nowadays, sensors are moving in the direction of micro, precision, and intelligence. Optical fiber sensors with electrical insulation, high precision, and micro-structure have become hot topics of research.According to the principle of fiber optic interferometer sensor and some practical applications, this paper designs and designs a new structure for welding microtubes to the reflection end of Michelson fiber interferometer. The main research is as follows:
Firstly, this paper analyzes the development history of Michelson interferometer and its research status and future development. In comparison with other interferometers and some practical applications, some shortcomings of fiber-optic Michelson interferometer sensors are found.Secondly, most of the current fiber-optic sensor manufacturing processes are complex and costly, which is not conducive to the popularity of fiber-optic sensors. Most of the ends of fiber-optic Michelson interferometer sensors are exposed to the air and are easily interfered by the external environment.Therefore, this paper combines some previous studies and some understanding of the fiber-optic Michelson interferometer to design a new fiber-optic Michelson interferometer sensor that fuses the silicon dioxide micro-tube structure on the fiber-reflecting end face.In addition, several common fiber optic interferometer sensors are described, describing some of the basic characteristics of Michelson interferometers.Furthermore, the design and fabrication process of a new type of end-reflection fiber Michelson interferometer sensor is introduced in detail.Finally, the temperature response and refractive index response were investigated experimentally, and the response sensitivity of temperature and refractive index was calculated.
Keywords:Fiber optic sensor; Michelson interferometer; temperature; refractive index
