Performance degradation of a Michelson interferometer when its misalignment angle is a rapidly varying, random time series

摘要

When subjected to random background vibrations, a standard, circular-aperture Michelson interferometer with a dynamic alignment servo system has a misalignment angle that is a random function of time-Here we derive formulas for the loss in performance when the misalignment angle is modeled as a stationary stochastic time series and show how these formulas are simplified when the power spectrum is band-limited white noise. # 1997 Optical Society of America
