摘要

倾斜光纤光栅的透射谱中除了纤芯模之外还有一系列包层模。倾斜光纤光栅各个模式的应变传感特性是不同的

因此

可将每一个模式作为一只应变传感器测量应变。提出了利用倾斜光纤光栅的多个模式作为应变测量的多只传感器

在此数据测量基础上

采用数据融合方法提高数据测量的精度

从而得到应变的准确信息。这种方法计算简便

编程容易

在实际测量系统中具有很好的应用价值。

Abstract

Apart from core mode

there are some cladding modes in transmission spectrum of titled fiber grating.The strain sensing character of each mode in tilted fiber grating is different

and so each mode can be used as a strain sensor to measure strain.For the first time

some modes in tilted fiber grating are used as sensore to measure strain

and on a basis of measurements

data fusion is used to improve the precision of measurement and to obtain the exact strain.This method has the advantages of simple calculation and easy programming.It has some application values in practice measurement system.
