摘要 提出了一种基于线型腔掺铒光纤激光器的光纤布拉格光栅传感解调系统,并进行了理论分析和实验验证。此传感系统具有稳定性好、信噪比高、结构简单等特点。实验结果表明:在常温下光纤光栅传感解调系统能很好的实现光纤光栅传感信号的传感和检测;15m掺铒光纤用作增益介质可以产生较大信噪比的稳定激光输出,系统在4nm范围内的解调精度为0.04nm。 A scheme of fiber Bragg grating wavelength demodulation band on Er-doped fiber lair is proposed and demonstrated. The cavity of the fiber laser consists of the sensor FBG and the tunable FBG, the Bragg period is tunable through a onedimensional adjustor. The one dimensional adjustor, which is connected with a step motor that is controlled by a PLC (Programmable logic controller), can control the laser to emit or riot through tuning the period of the tunable FBG. The tuning module, the O/E circuit and the detecting-and-controlling system construct a close loop, which controls the performancc of tbe wavelength demodulation. The experiment resuh shows that the precision of the proposed system is about 0.04nm in a range of 4nm.
