摘要
利用可调光纤F-P滤波器作为解调元件建立了光纤光栅温度解调系统,采用数字信号处理器外部中断实现反射谱峰值的准确定位。光纤光栅温度解调实验结果表明,解调系统的测量精度得到了提高。
The tuneable fiber Fabry - Perot filter is used as demodulation device to set up fiber grating temperature demodulation system, and data signal processor(DSP) is used to carry out the exact orientation of peak value of reflective spectrum by external interrupt. The results of FBG temperature demodulation experiment show that the measuring precision of demodulation system is improved.
