FUNDAMENTAL PROBLEMS IN METROLOGY RESONANT GRAVITATIONAL ANTENNAS: ZERO-POINT FLUCTUATIONS OF AN EVACUATED OPTOMECHANICAL CONVERTER CONTAINING AN ABSORBING MIRROR

摘要

A fine structure is considered for the zero-fluctuations of the vacuum in an optomechanical converter containing an absorbing mirror as sensing element for resonant gravitational antennas. A formula is given for the threshold sensitivity of such an antenna in relation to the absorption coefficient in optimal data processing.
