Abstract:
An image-reproducing apparatus for reproducing an image from a hologram or a holographic stereogram, which records either 2-dimensional image data or 3-dimensional image data,wherein an optical member having parallel prisms on a front surface is bonded at the rear surface to the hologram or holographic stereogram, and illumination light is applied to the front surface of the optical member, thereby to reproduce a 2- or 3-dimensional image from the hologram or holographic stereogram, wherein the optical member has a plurality of incidence surfaces on the front surface, and the illumination light is applied at right angles to the incidence surfaces of the optical member, and wherein the hologram or holographic stereogram and the optical member bonded thereto are bent, forming a hollow cylinder, the inner surface of which is defined by the front surface of the optical member, and the illumination light is applied to an inner surface of the hollow cylinder, thereby reproducing a 2- or 3-dimensional image from the hologram or holographic stereogram.
