| 摘 要： | 在介绍干涉型光纤传感器的相位载波解调技术(PGC)原理的基础上,采用Labview开发软件对偏振无关干涉型光纤传感器进行了数字化解调。结果显示,采用0.08rad1kHz的单频模拟信号,解调后系统信噪比(SNR)为55dB。实验证实,基于Labview语言和数据采集卡的PGC解调,能完整真实的解调出待测信号,并具有噪声低,调试方便,可视化等优点。

| Abstract: | Based on phase generated carrier demodulation technique (PGC),the demodulation process of the polarization-insensitive interferometric optical fiber sensor is digital simulated by Labview.The experiment result shows that,using the single simulation signal of 0.08 rad 1 kHz,the system SNR is 55 dB.The experiment result indicates that by using Labview and data acquisition card,the signal can be demodulated correctly,and the PGC demodulation process has the advantages of low-noise,the convenience of debugging,... |
