标题： Double Michelson/Fabry-Perot interferometer for laser- and displacement-noise-free gravitational-wave detection

摘要： 在本文中，我们证明，如果满足某些模型假设，带有臂部法布里-珀罗腔的双迈克尔逊干涉仪能够实现无激光噪声和位移噪声的引力波（GW）探测。假设单个迈克尔逊/法布里-珀罗干涉仪的输入镜可以刚性地连接到中心平台上的分束器，就可以以一种方式操控干涉仪的响应信号，从而消除所有测试质量的激光噪声和位移噪声，除了中心平台。一对对称放置且具有共同中心平台的迈克尔逊/法布里-珀罗干涉仪可以对后者不敏感，从而允许完全无激光和位移噪声的干涉测量（DFI）。证明了所提出干涉仪的DFI响应与$f^2_{\textrm{gw}}/\gamma$成正比，其中$\gamma$是腔体半带宽，即广义相对论允许的最强DFI响应。 显示英文摘要

摘要： In this paper we demonstrate that a double Michelson interferometer with Fabry-Perot cavities in its arms is able to perform laser- and displacement-noise-free gravitational-wave (GW) detection if certain model assumptions are met. Assuming the input mirrors of a single Michelson/Fabry-Perot interferometer can be rigidly attached to beamsplitter on a central platform one can manipulate with interferometer's response signals in a way to cancel laser noise and displacement noise of all test masses except the cental platform. A pair of symmetrically positioned Michelson/Fabry-Perot interferometers with common central platform can be made insusceptible to the later then, thus allowing complete laser- and displacement-noise-free interferometry (DFI). It is demonstrated that the DFI response to GWs of the proposed interferometer is proportional to $f^2_{\textrm{gw}}/\gamma$, where $\gamma$ is the cavity half-bandwidth, that is the strongest DFI response allowed by general relativity.
