M. Bernardini et al., DISPLACEMENT MEASUREMENT IN VIRGO SUPER ATTENUATORS WITH A SUSPENDED FABRY-PEROT-INTERFEROMETER, Nuclear physics. B, 1997, pp. 179-183
The use of a two mirrors Fabry-Perot suspended cavity as a high sensit
ivity displacement detector is considered. It can be used to test the
remnant noises in VIRGO Super Attenuators. The displacement sensitivit
y of the apparatus should be increased up to the mirrors thermal noise
limit.
