基于引力波和测试质量运动对光传播的影响不同这一事实，我们提出了一种新的想法，使我们能够在不受任何位移噪声干扰的情况下探测引力波。我们通过分析一个简单的玩具模型来证明这个想法，这个模型由三个在一条线上相等分开的物体组成。通过对这些物体之间的光传播时间进行一定的组合，我们构建了一个不受每个物体位移影响的观测值，它对引力波具有合理的灵敏度。
We present a new idea that allows us to detect gravitational waves without being disturbed by any kind of displacement noise, based on the fact that gravitational waves and test-mass motions affect the propagations of light differently. We demonstrate this idea by analyzing a simple toy model consisting of three equally-separated objects on a line. By taking a certain combination of light travel times between these objects, we construct an observable free from the displacement of each object, which has a reasonable sensitivity to gravitational waves.
