| 摘 要： | 研制一种利用光纤的闭环液位控制系统，光纤探针是由两根多模光纤焊接在一起形成的，光纤探针边界处的光线对周围介质的折射率敏感，系统使用两个光纤探针将液位控制在相应的范围内，设计的液位控制系统很好地解决了液滴效应带来的延迟问题。

| Abstract: | A simple optical fiber closed-loop liquid-level control system is described.The sensor head is made of two fusion-spliced multimode fibers and the light at its boundary is sensitive to the refractive index of the surrounding medium.Two sensor heads are used to control the water level within a range corresponding to the two sensors' positions.Droplet formation problem is well dealt with in this sensor. |
