摘要：
We present a new signal-extraction scheme based on harmonic demodulation for control of a power-recycled interferometric gravitational-wave detector. Demodulation at the third-harmonic frequency of a frontal phase modulation is used to robustly extract well-separated longitudinal signals. (C) 2000 Elsevier Science B.V. All rights reserved.
