Vibration measurement without the Heydemann correction
We propose a novel signal-processing technique to avoid cyclic errors in laser interferometers instead of an elliptical fitting, known as the Heydemann correction. It is based on a simple superposition of background motions to average out the effect of cyclic errors. With a simulation, we show that...
