Abstract
Theoretical and experimental analysis of two methods for obtaining time average holographic interferometry in Fourier plane was done. The fringe patterns are always localized in Fourier plane. From one hologram, it is possible to obtain simultaneously all components of vibration amplitude vector on the entire surface of the object. In both methods, the measuring range can be controlled by the parameters of the Fourier lens and covers tens to hundreds micrometers for in-plane vibrations and hundreds to thousands micrometers for out-of-plane vibrations.
