目前,用于溶液折射率测量的几种光纤传感器其型式和结构有所不同,但测量原理,都是基于光波在分界面处的能量传播规律。 本文介绍:(1)U形和V形光纤传感器;(2)用棱 At present, the types and structures of several kinds of optical fiber sensors used to measure the refractive index of solution are different, but the measurement principle is based on the energy propagation law of the light wave at the interface. This article describes: (1) U-shaped and V-shaped optical fiber sensors; (2) with ribs
