| 摘 要： | 提出并实现了一种基于FFP可调滤波器的FBG解调系统。该系统通过PC104嵌入式系统控制的D/A输出信号,作为可调滤波器的控制信号,对光纤上的所有光栅连续扫描以实现波长信号的解调。该解调系统扫描带宽50nm,以10Hz频率进行扫描,可以得到稳定的测量信号。

| Abstract: | A FBG demodulation system based on FFP tunable filter is proposed and demonstrated. In the system ,the D/A output signal is controlled by the embedded system PC104 and works as the control signal of an adjustable tunable filter. It continuously scans all the grating on the fiber, so as to demodulate the wavelength signal. This demodulation system has a scanning bandwidth of 50 nm. It scans at a frequency of 10 Hz and gets a stable output. |
