提出了一种利用对称金属包层光波导中的超高阶导模进行位移测量的改进方案。基于这一思想，结合锁相放大技术，实验证明了一种具有稳定的位移分辨率为3.3 pm的传感器，而无需任何复杂的伺服系统。
An improved scheme for displacement measurement using the ultrahigh-order guided modes in a symmetrical metal-cladding optical waveguide is proposed. Based on this idea together with the lock-in amplification technique, a sensor with a stable displacement resolution of 3.3 pm is experimentally demonstrated without any complicated servo system.
