最近发明的位移噪声的引力波探测方案的动机，我们证明了存在的引力波探测方案不受位移和定时（激光）噪声的影响，从而实现了散粒噪声限制的激光干涉。这可能是由于两个原因：第一，引力波和位移扰动以不同的方式对光传播时间的贡献;第二，对于N探测器系统，信号通道的数量是O微米（N（2））的数量级，而定时和位移噪声通道的总数是O微米（N）的数量级。
Motivated by a recently invented scheme of displacement-noise-free gravitational-wave detection, we demonstrate the existence of gravitational-wave detection schemes insusceptible to both displacement and timing (laser) noises and are thus realizable by shot-noise-limited laser interferometry. This is possible due to two reasons: first, gravitational waves and displacement disturbances contribute to light propagation times in different manners; second, for an N-detector system, the number of signal channels is of the order Omicron(N(2)), while the total number of timing- and displacement-noise channels is of the order Omicron(N).
