An interferometric device to measure the mechanical transfer function of the VIRGO mirrors suspensions

Abstract: The design of servoloops for automating alignment and locking of long baseline gravitational wave detectors requires an accurate knowledge of the mechanical transfer function (TF) of the mirror suspensions. We present a suspended interferometric device devoted to the measurement of the TF of the multipendular seismic isolators of the VIRGO antenna.
