The records of the acoustical holography imaging of 60 cm concrete cube model have been taken with the predetermined model lead intrusions. Both phase and amplitude holograms were obtained. Their numerical reconstruction enabled to visualize the cross-shaped structure of this model intrusion. The records for seismic imaging of near-surface objects were taken in the region of Barbara Experimental Mine, Mikolow, Upper Silesia region, Poland. The method of seismic transmission holography was used. The explosives were detonated at one point on the depth of 40 m and signals were recorded on the surface lattice of 21 X 21 points on 50 m square. These signals were further processed to obtain phase and amplitude holographic data. The seismic holograms synthesized in such a way that were numerically reconstructed. The Z-shaped image of the part of mine's gallery on the depth of 20 m was obtained.
