| 摘 要： | 建立并确定了基于FBG传感器多参数同时测量系统数学模型,提出用矩阵条件数结合测量公式导出矩阵条件数与温度、压力测量公式间的矩阵的关系式,利用该关系式可以去除病态矩阵参数并可以找出最佳镀层材料及厚度以此来提高FBG传感器的测量精度.实验表明,当镀有不同厚度铜,且r2≤0.4mm时FBG测量温度和压力都具有较高的灵敏度.

| Abstract: | The FBG sensor based on multi-parameter mathematical model of simultaneous measurement of the system was established and determined.The condition number of matrix was proposed to deduced the relationship between the formula of coated-thickness and coated-materials and the condition number of matrix.The ill-conditioned matrix parameters can be removed,and the best coated-material and coated-thickness with improving the measurement accuracy of FBG sensors was found.As indicated by the experiment,the FBGs sensitivities is higher with coated with different thickness of copper,and r2≤0.4 mm. |
