We report an extrinsic Fabry-Perot-type optical-fiber interferometric sensor system constructed by using multimode optical fibers. The intermodal noise produced by the multimode optical fibers was suppressed by the use of optical-fiber white-light interferometry and by the consideration given to the sensor-head design. Both a theoretical analysis and an experimental investigation were carried out, and a system signal-to-noise ratio of 45 dB was demonstrated.
我们报道了一种通过使用多模光纤构建的外在法布里-珀罗型光纤干涉传感器系统。通过使用光纤白光干涉测量法以及考虑传感器头的设计，抑制了多模光纤产生的模间噪声。进行了理论分析和实验研究，证明系统信噪比为45分贝。
