提出了一种基于对称金属包层光波导增强型古斯汉兴（G-H）效应的振荡波位移传感器。由于检测信号与入射光功率波动无关，G-H位移的幅度被增强到数百微米，因此在我们的实验中，在不使用任何复杂的光学设备和伺服技术的情况下，证明了40 pm的分辨率。
An oscillating wave displacement sensor based on the enhanced Goos-Hänchen (G-H) effect in a symmetrical metal-cladding optical waveguide is proposed. Since the detected signal is irrelevant to the power fluctuation of the incident light and the magnitude of the G-H shift is enhanced to hundreds of micrometers, a 40 pm resolution is demonstrated in our experiment without employing any complicated optical equipment and servo techniques.
