The holographic interferometer sensitivity to the transverse or longitudinal motions of a plane surface diffusely scattering incident light is analyzed. It is shown, that the interference patterns are localized in the hologram plane and in the plane of the pupil image formed by a positive lens, with the help of which the hologram recording is being carried out. To record the holograms, a spatial filtering of the diffraction field is needed. The experimental results well agree with the theory.
