FIELD: printing industry.
SUBSTANCE: each elementary hologram is recorded by the interference of signal and a set of reference beams which are placed on an imaginary conical surface continuously with respect to each other, and the reference beams are converged of the recording medium. When reconstruction of the hologram a beam of rays from a point source of white light is used, which angle of incidence is changed in the azimuthal direction in the range of 2π radians. For formation of a set of reference beams axicon - circular diffraction grid is used.
EFFECT: method enables to observe the reconstructed image from any angles.
