精密干涉测量的许多应用在知道空气折射率或激光波长的值时存在不确定性，通常需要使用复杂的设置或昂贵的组件来减轻这些影响。在这项工作中，使用距离分辨干涉测量，我们展示了如何使用沿单个光束的差分测量来执行位移测量，并大大减少了系统误差。在原理验证实验中，安装在移动平台上的半透明目标被放置在窗户和镜子之间的中央，在目标周围形成两条名义上长度相等的空气路径。然后，在沿测量波束的多个位置处的干涉相位信号的评估允许同时测量目标两侧上的两个空气路径的长度的变化。空气路径长度变化的差异产生了期望的目标位移测量，同时强烈抑制了两个空气路径共同的影响，如空气折射率变化或激光波长漂移。
Many applications of precision interferometry suffer from uncertainties in knowing the values of the air refractive index or the laser wavelength and often require the use of complex setups or costly components to mitigate these effects. In this work, using range-resolved interferometric measurements, we show how differential measurements along a single optical beam can be used to perform displacement measurements with drastically reduced systematic errors. In a proof-ofprinciple experiment, a semi-transparent target mounted on a moving stage is placed centrally between a window and a mirror, forming two air paths around the target that are arranged to be of nominally equal length. The evaluation of the interferometric phase signals at multiple locations along the measurement beam then allows the simultaneous measurement of changes in the length of the two air paths on either side of the target. The difference of the air path length changes yields the desired target displacement measurement, while influences that are common to both air paths such as air refractive index changes or laser wavelength drift are strongly suppressed.
