    Abstract: 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.

    Abstract: In a system of detecting an interference light with a light not irradiated onto an optical disc to increase the S/N ratio, it is difficult to stably acquire a reproduced signal with a simple configuration. Since the recording density is not improved, an improvement in transfer rate is difficult. In an optical information recording/reproducing apparatus where two optical beams face each other and are focused at the same place of a recording medium to record a standing wave developed by interference of the two optical beams, a phase difference of the two optical beams is modulated in a multiple stage and recorded. During reproduction, an interference light of a reproduced light from the recording medium and another reproduction reference light is detected as a reproduced signal, and a phase servo control stabilizing the phase of interference during reproduction by using a low frequency component of the reproduced signal is conducted.

    Abstract: Hybrid white-light viewable holograms and methods for making them. The holograms are hybrid reflection holograms made using the diffractive structures or gratings of a holographic object such as a transmission hologram or holographic optical element (HOE). The wavefronts of the diffractive structures are converted into a reflection hologram by scanning them with a coherent light source having a profiled narrow beam. The hybrid reflection hologram can exhibit display parameters including the multiple colors, solidity, and color stability of white light reflection holograms, the diffractive color shifting of a white light transmission hologram, three dimensional imaging and a wide variety of dynamic changes. Different areas or images with each of these effects can be combined in a single hologram. These hybrid reflection holograms are ideal for security and forgery prevention applications.

    Abstract: A technique for recording data onto a hologram recording medium using spatial light phase modulation corresponding to the recording data, and a technique for reproducing recorded data by properly reading information on phases recorded on a hologram recording medium. A signal beam having a phase modulation pattern corresponding to recording data and a reference beam having a specific phase modulation pattern are applied to the recording medium. Thus, recording data can be recorded onto the hologram recording medium using phase information. In addition, at the time of reproduction, a reference beam and a direct current (DC) beam, whose phase difference with respect to the reference beam is π/2, are applied to the hologram recording medium. By reading the reproduction beam to which the DC beam is added, recorded information on phases can be correctly read, and recorded data can be reproduced in accordance with the phase information.

    Abstract: A volume hologram recording material is located on the side of a reflection type volume hologram master onto which copying illumination light is incident, and the copying illumination light incident onto the recording material and light diffracted through the master interfere together in the volume hologram recording material thereby copying the reflection type volume hologram master. In this case, a reflecting plate having a fine regular reflection pattern is interleaved between the master and the recording material, and the copying illumination light incident onto the recording material and regularly reflected light from the reflecting plate having the regular reflection pattern interfere together in the recording material thereby allowing the regular reflection pattern to be multi-recorded in a hologram having the reflection type volume hologram master copied in it.

    Abstract: 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.

    Abstract: A recording technique for performing data recording onto a hologram recording medium in accordance with information on phases by performing spatial light phase modulation as spatial light modulation corresponding to recording data, and a reproducing technique for reproducing recorded data by properly reading information on phases recorded as described above are suggested. A signal beam having a phase modulation pattern provided thereto corresponding to recording data and a reference beam having a specific phase modulation pattern provided thereto are applied to the hologram recording medium. Thus, recording data can be recorded onto the hologram recording medium in accordance with information on phases. In addition, at the time of reproduction, a reference beam and a DC beam having the entire phase whose phase difference with respect to a reference phase within the reference beam is π/2 are applied to the hologram recording medium. By providing a phase difference based on π/2 as described above, the phase of a reproduction beam obtained from the hologram recording medium in accordance with application of the reference beam and the phase of the DC beam can be set to be the same. Thus, the DC beam can be added as a component of an amplitude of “1” to the reproduction beam. By reading the reproduction beam to which the DC beam is added as described above, recorded information on phases can be correctly read, and recorded data can be reproduced in accordance with the phase information.
