一种增强LPG温敏特性的方法

Method of enhanced the temperature sensitivity of LPG

在长周期光栅的测温原理基础上,介绍了一种增强长周期光栅测温灵敏度的方法——使用高热光系数的折射率匹配液CargilleRIoil浸涂长周期光栅,使其温度灵敏度得到显著的提高。

Basing on the principle of temperature measurement of LPG, introduced in this paper is a new method to enhance temperature sensitivity in an LPG. That is to coat an LPG with Cargille RI oil which is of high thermo-optic coefficient. Temperature sensitivity of the LPG can therefore be enhanced remarkably.
