高灵敏度镀膜拉锥光纤液体折射率传感器
High sensitivity liquid refractive index sensors of the coated tapered fiber
摘要
Abstract
This paper investigates a kind of fiber refractive index sensor which has the advantages of high measuring accuracy,by introducing reflective elements into the cladding layer.The paper analyzes the different effects of various factors on the sensitivity of the tapered optical fiber.By the way,in order to improve the sensitivity of the system,the reflection element (gold-plated) is introduced at the end of the tapered fiber,then the sensing area of the coated tapered fiber is immersed in liquid which with different refractive index,and analyzes the shift of optical transmission spectrum.关键词
