FIELD: holography, optics. SUBSTANCE: hologram recording process involves illumination of object of holography by coherent light beam followed by reflection of this beam from object of holography with formation of object wave field, action on light-sensitive material with object and reference wave fields and subsequent processing of light-sensitive material with obtainment of hologram that presents volumetric holographic grating. Illumination of the latter reconstructs object wave filed which is holographic image. Coding of object wave field is carried out by creation of deformation sections on surface of object of holography and light-sensitive material with deformation value chosen from range 0.1- 1.0 μm visualized on reproduced holographic image while hologram is illuminated by coherent light beam with purpose of copying. EFFECT: enhanced efficiency of process. 4 cl, 3 dwg
