The distorted wave front of the light that is diffusely reflected from the rough surface is restored by phase conjugation to provide an interference signal with a high signal-to-noise ratio. The vibration amplitudes of a stainless-steel sample are measured with a precision of approximately 5 nm.}, pages = {4593--4597}, title = {Measurement of small vibration amplitudes of a rough surface by an interferometer with a self-pumped phase-conjugate mirror}, volume = {30}, year = {2000} }
