摘要： The invention is concerned with a volume hologram medium obtained by multiple recording of holograms, which is improved in terms of just only security for forgery prevention but also aesthetics. A volume hologram medium 29′ comprises a reflection hologram in which a stereoscopic image of a three-dimensional object and an image of a plane pattern of a mask plate are recorded by interference of the same reference light beams having the same angle of incidence and the same wavelength with object light beams having mutually different angles of incidence. The stereoscopic image of the three-dimensional object is reconstructed in the form of diffracted light 31 in a singlecolor and in angle relations close to recording conditions, and the image of a plane pattern of the mask plate is reconstructed as diffracted light 32b, 32′b at various angles of incidence of white illumination light 30 and in different colors depending on those angles of incidence. Thus, more improved aesthetics are achievable, and more enhanced security is ensured by determination of whether or not the volume hologram medium has such aesthetic properties.

摘要： An optical diffusing sheet is provided, which prevents deterioration in image quality which might result from warping of the sheets due to environmental changes, and is capable of, even if a substrate is broken by an accident, preventing scattering of pieces of the broken substrate. An optical diffusing sheet is used in a transmission type screen that emits imaging light projected from an incident side to an emergent side. The optical diffusing sheet includes a highly rigid substrate layer with a light-transmissibility and a high rigidity, and a plurality of layers laminated on the highly rigid substrate layer. The plurality of layers includes at least a pair of anti-scattering layers disposed on opposite sides of the highly rigid substrate layer for preventing scattering of the highly rigid substrate layer. At least one layer of the two or more layers includes an optical diffusing element that diffuses imaging light.

摘要： A hologram recording film has an image of a three-dimensional object, e.g. a three-dimensional model, recorded in a volume hologram photosensitive material and further has a hologram image of a plane color pattern, e.g. a character or an image, together with the shadow of the color pattern, recorded as individual information in a superimposed manner in the same photosensitive material without using a liquid crystal display. Pieces of plane additional information of the same pattern have been recorded so as to be capable of being reconstructed simultaneously in a hologram plane and in front of or behind the hologram plane, respectively, in superimposition with a reconstructed image from a volume hologram.
