摘要：

Recent measurements at the LIGO Hanford Observatory have confimed the predicted high-frequency dynamic response of km scale Fabry-Perot cavities to length and laser frequency variations. The dynamic response functions have been exploited to determine a number of cavity parameters including the cavity length and the resonance width. A new technique based on a variation of these measurements has been utilized to measure the interferometer ann cavity lengths with a precision of 80 mum. We present an overview of these measurements and discuss how the dynamic field responses could be used to measure the cavity g factors which are related to the mirror radii of curvature.
