摘要
光纤传感器系统中,由于色散元件的存在,光源中心波长随温度的漂移将给系统带来误差.在对IM85-I型光纤压力传感器系统的色散特性作了详细分析的基础上,采用软件补偿的方法以消除温度变化给系统带来的误差.实验结果表明,进行温度补偿后,系统的稳定性有明显的提高.
In many optical fiber sensors, any drifts in the wavelength of the source which are due to changes in ambient temperature will induce errors. By theoretical analysis and experiment, this error can be reduced using software compensatory method.
