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.
