| 中文摘要: |
| 基于拉曼散射的分布式光纤测温系统应用于火灾监测有独特的优势，弥补了传统感温探测器的不足。介绍了基于拉曼散射的测温原理及基于光时域的空间定位原理，并进行了火灾预警实验，实验结果表明在建筑物高度在一定范围内，基于拉曼散射的分布式光纤测温系统可以很好地实现火灾预警功能。 |
| 英文摘要: |
| For application in fire monitoring, the distributed optical fiber temperature measurement system based on Raman scattering has a unique advantage of making up for the deficiency of the traditional thermal detector. This paper introduces the temperature measurement principle based on Raman scattering and space positioning principle based on optical time domain. A fire warning experiment was carried out, which showed that the distributed optical fiber temperature measurement system based on Raman scattering can well realize fire warning function for building heights within a certain range. |
