title: Limitation of the observable surface acoustic wave amplitude in frequency-shift holography.
abstract: The theoretical and experimental analysis of the limitation of the observable amplitude of surface acoustic waves in a frequency-shift holography is presented. In this holography technique the object beam is filtered optically, and the frequency of the reference beam is shifted by the same amount as that of the surface acoustic wave. Several parameters that determine the limitation are analyzed, and a subangström amplitude has been observed experimentally.
