Реферат: METHOD FOR CONSTRUCTING AND RECONSTRUCTING HOLOGRAM ABSTRACT OF THE DISCLOSURE A method for constructing and reconstructing a hologram. The hologram is constructed by irradiating two construction beams having a different incidence angle onto a hologram record medium and forming inter-ference fringe patterns therein by the two construction beams. The hologram is reconstructed by irradiating a reconstruction beam onto the interference fringe patterns so as to diffract the reconstruction beam in accordance with the interference fringe patterns. At least one of the two construction beams irradiates the hologram record medium through at least one optical deviation element. The incidence angle of the reconstruction beam is different from that of each construction beam and arranged to be nearly a Bragg angle at any point of the hologram.
