通过组合多个探测器信号来消除其测试质量的所有位移噪声并保持引力波（GW）信号的干涉仪设计被称为无位移噪声干涉仪（DFI）。这个想法已经考虑过以前的激光干涉仪。然而，激光DFI的局限性在于其敏感频带对于天体物理GW源来说太高，即使对于更大尺寸的干涉仪也是如此。为了规避这一限制，在本文中，我们提出了一种中子DFI，其中使用中子而不是光。由于中子的速度比光速低得多，中子DFI的敏感频带可以降低到。因此，中子DFI可用于探测地面上普通激光干涉仪无法探测到的GWs。
An interferometer design that cancels all displacement noises of its test masses and maintains a gravitational-wave (GW) signal by combining multiple detector signals is called a displacement noise-free interferometer (DFI). The idea has been considered previously for a laser interferometer. However, a limitation of a laser DFI is that its sensitive frequency band is too high for astrophysical GW sources,even for a kilometer-sized interferometer. To circumvent this limitation, in this paper, we propose a neutron DFI, in which neutrons are used instead of light. Since neutrons have velocities much lower than the speed of light, the sensitive frequency band of a neutron DFI can be lowered down to. Therefore, a neutron DFI can be utilized for detecting GWs that are inaccessible by an ordinary laser interferometer on the ground.
