    Abstract: A hologram recording method is a method of recording a hologram, on a hologram recording apparatus that records information by forming a diffraction grating through oppositely irradiating the signal beam and the reference beam to the hologram record carrier. The hologram recording method includes a step of focusing the reference beam at a first numerical aperture from a first effective diameter by means of the reference-beam objective lens, a step of separating the reference beam in a part on the optical axis and a neighborhood thereof to thereby produce from the reference beam a recording reference beam to passes through the hologram record carrier at a second numerical aperture smaller than the first numerical aperture from a second effective diameter smaller than the first effective diameter by means of the reference-beam objective lens of the reference-beam optical system, and allowing the recording reference beam to exit coaxially to the reference beam, and a step of not allowing only the recording reference beam to exit toward the hologram record carrier by means of the signal-beam optical system.

    Abstract: A photosensitive film for holographic recording and its production method thereof are disclosed. The film comprises a base film, a buffer layer coated on one side of the base film, a photosensitive polymer coating layer formed by applying a photosensitive coating on the other side of the buffer layer, and a surface protective film covering the surface of the photosensitive polymer coating layer. Interference fringe patterns of a holographic image or an amphichronic graph are recorded in the photosensitive polymer coating layer. The film according to the present invention is a photosensitive material composed of two polymers of different refractive indexes, when coherent light beams intersect in its recording medium and produce an interference fringe pattern in the medium, monomers therein are excited accordingly and undergo free radical polymerization, thereby forming a hologram.

    Abstract: The invention relates to a method and a device for producing a hologram in an optical medium, particularly for storing data in the optical medium. In the method, the hologram is produced in the optical medium using laser beams, wherein the laser beams are formed from a laser beam emitted by a free-running semiconductor laser, are directed onto the optical medium, optionally contradirectionally, and at least partially spatially overlap in the optical medium. For producing holograms using inexpensive components with a high contrast, the invention provides for arranging the reflection unit (15) such that the optical path length (Δx) between the focus of the laser beam in the storage medium (10) and the reflecting surface of the reflection unit (15) satisfies the condition Δx=0.5*Δs*a in the region of the optical axis, wherein a is a natural number greater than or equal to 1 and Δs is a distance between neighboring coherence centers of the laser beam produced by the semiconductor laser (16).

    Abstract: A simplified method is provided for recording identification information, such as a serial number or the like, in a hologram-recorded film simultaneously with hologram duplication. The method includes the steps of coupling a hologram recording film with a master hologram plate having a master hologram, the master hologram plate having a reflective area adjacent the master hologram; and directing laser beams towards the master hologram plate to induce interference between incident laser light and diffraction laser light from the master hologram in the recording film, at least some of the laser beams radiating the reflective area through a transmission type controllable display device to record a pattern in the hologram recording film corresponding to a pattern displayed at the transmission type controllable display device.
