Substantially two-dimensional objects are holographically recorded and reproduced by directing a light beam of a spherical reference wave onto one side of a planar hologram carrier and directing the object wave upon the opposite side, the object being centered upon the normal which passes from the wave center of the reference wave onto the hologram carrier which is larger, preferably very much larger than the object. The hologram photographically recorded on the carrier is reproduced by directing toward the hologram carrier a spherical reproducing wave whose wave center location relative to the hologram carrier is coincident with that of the reference wave used for recording, but whose directional propagation is opposed to that of the reference wave.
