title: Resonant speed meter for gravitational-wave detection.
abstract: Gravitational-wave detectors have been well developed and operated with a high sensitivity. However, they still suffer from mirror displacement noise. In this Letter, we propose a resonant speed meter as a displacement noise-canceled configuration based on a ring-shaped synchronous recycling interferometer. The remarkable feature of this interferometer is that, at certain frequencies, gravitational-wave signals are amplified, while displacement noises are not.
