Abstract
In a multimode detector of gravitational radiation, the displacements induced in the antenna by the gravitational field can be amplified by many orders at the last resonator. Detection of the displacements of that resonator with a Fabry–Perot interferometer is considered. Quantum and classical sources of noise are analyzed and specifications for laser instrumented massive wideband systems operating at the level of δh=2.6×10−20 and 3×10−22/(Hz)1/2 are given. Three detectors could be used to cover the frequency range ≊400–≊1200 Hz with approximately uniform sensitivity.This publication has 6 references indexed in Scilit:
