Combined interferometer system for displacement measurement
Abstract
A displacement-measurement system has been devised by combining two Fabry-Perot interferometers (FPIs). This system possesses the high limiting resolution of a multibeam interferometer and allows a considerable relaxation of the source frequency-stability requirements as compared with a laser interferometer (LI) based on a single FPI. The combined system is suitable for implementation in LI gravitational-wave detectors.
