| 摘 要： | 提出一种新型的光纤测温传感器。基于热胀冷缩原理,物体长度会随温度变化产生与之成正比的微小变化,采用带光源的光纤测微位移探头测出这个微小变化,可得温度与位移的变化关系,采用光电转换则可输出温度与电流的变化关系。

| Abstract: | A novel type of optical temperature sensor is designed. On the basis of material expansion and contract property, the material will expand or contract a little when the temperature rises or drops. Detecting this tiny displacement by using optical fiber micro-displacement detector with lamp-house, the relation between temperature and displacement is found. Then by using photoelectric transformation, the relation is got between temperature and current output. |
