暴露在离子辐射环境中的光纤会产生感生传输损耗,辐照后,需若干年才可恢复.在如此长的时间内进行辐照感生损耗的特性测量是十分困难的,但是预测光纤长时间暴露在离子辐射环境(如反应堆、医学应用、航天仪表或加速器仪表)中的光纤性能是很有必要的.本文概要介绍北大西洋公约组织(NATO)第5小组的许多实验人员、核效应试验团体(NETG)第12研究小组关于光时域反射仪进行这些测量的适用性研究.结果表明,只要按照推荐的准则使用,该方法是有效的.
Optical fibers exposed to ionizing radiation have induced transmission losses that take years to recover.It is difficult to measure the characteristics of irradiation induced loss over such a long period of time, but the predicted fiber length Time exposure to optical fiber performance in ionizing radiation environments such as reactors, medical applications, aerospace instruments, or accelerometers is essential. This article outlines many of the experimenters of NATO Group 5, the Nuclear Effects Experiment The Applicability Study of Group 12 (NETG) Study Group 12 on Optical Time Domain Reflectometry for these measurements showed that this method was effective whenever used in accordance with the recommended guidelines.
