TLDR
A tabletop experiment is described that demonstrates a scheme for extracting signals in such an interferometer corresponding to deviations from perfect interference.Abstract:
Large-scale gravitational-wave detectors currently under construction such as the LIGO detectors use multiple-mirror resonant optical systems containing several surfaces at which the relative phase of interfering light beams must be controlled. We describe a tabletop experiment that demonstrates a scheme for extracting signals in such an interferometer corresponding to deviations from perfect interference.read more

TL;DR: In this paper, the laser interferometer gravitational wave observatory (LIGO) project's 40 m inter-ferometer has been improved through two major instrumental improvements: improved vibration isolation has reduced the noise due to ground motion and test masses with less mechanical dissipation were installed to lower the thermal noise associated with mirror vibrations.
