光时域反射计量的快速和定位精度在探测管道的泄漏中找到新应用。能源和化学公司现在从车辆和直升飞机上以目视检查管道,但难于发现泄露。为了很快停止泄漏,理想的解决办法是用传感器引导工人到问题出现处。曼彻斯特科技大学的Ｆ.Ｋｏｖａｓｉｎｋ认为他可用光纤传感器解决这个 The speed and positioning accuracy of optical time-domain reflectometry find new applications in detecting leaks in pipes. Energy and chemical companies now visually inspect ducts from vehicles and helicopters, but find it harder to find leaks. In order to stop the leak quickly, the ideal solution is to use sensors to guide workers to where the problem occurs. F.Kovasink of Manchester University of Technology thinks he can solve this with a fiber optic sensor
