我们提出了基于光纤的干涉测量的几十纳米级的动态位移,使用相位调制的参考光与逐步控制的操作点的调制(OPM)。它既不需要预先调整的OPM,也不反馈控制的干涉仪的光程差。通过使用相位调制器作为样本来模拟机械振动,对系统进行定量评估。即使当光纤干涉仪被故意扰动时,也可以测量100 kHz振动的动态位移,其振幅为19 nm,这证实了所提出的方法的有效性。
We propose the fiber-based interferometric measurement of tens-of-nanometer-scale dynamic displacement that uses phase-modulated reference light with stepwise control of the operation point of modulation (OPM). It requires neither the pre-adjustment of the OPM nor feedback control for the path-length difference of the interferometer. Quantitative evaluation of the system is performed by using a phase modulator as a sample to simulate mechanical vibration. The dynamic displacement for 100-kHz vibration with an amplitude of 19 nm is measured even when the fiber interferometer is intentionally perturbed, which confirms the effectiveness of the proposed method.
