    摘要: A holographic display system for generating a super hologram with full parallax in different fields of view in the horizontal and vertical directions. The system includes an array of holographic display devices, e.g., spatial light modulators (SLMs), operable to provide a plurality of holographic images of a scene from differing viewpoints of the scene. Each SLM is operated concurrently to output a narrow field of view, elemental hologram. The system includes coarse integral optics combining the holographic images into a single hologram (“super hologram”) viewable in a hologram image plane a distance from the course integral optics. The coarse integral optics combine the holographic images by providing angular tiling of the holographic images, e.g., bending the axes of parallel lenses. In this manner, the field of view, in one direction, of the super hologram is based on the number of holographic display devices provided in the array in one direction.

    摘要: Devices and methods for recording and reproducing a holographic 3D image are provided. The devices for recording the holographic 3D image comprising: a laser generation unit for emitting a laser beam; a beam splitter unit configured to receive the laser beam from the laser generation unit and split the laser beam into a reference beam and an object beam directed to an object to be photographed; a photorefractive crystal configured to receive the reference beam from the beam splitter and the object beam diffused from the object to form a holographic 3D image; and a rotation unit configured to rotate the photorefractive crystal once every time one holographic 3D image is recorded. The holographic 3D image can be recorded and reproduced by the rotate the photorefractive crystal in light paths of recording and reproduction light beams, respectively.

    摘要: A hologram device includes: a support section that keeps hold of, to be able to be attachable and removable, a hologram record carrier including a hologram recording layer stored therein with an optical interference pattern of a coherent signal light and a coherent reference light as a diffraction grating; a light source that generates the coherent reference light; a signal light generation section that is disposed on an optical axis, and generates the signal light by modulating the reference light in accordance with recording information; and an interference section that is disposed on the optical axis, and forms the diffraction grating being the optical interference pattern inside of the hologram recording layer by directing the signal light and the reference light toward the hologram recording layer. The signal light generation section is provided with a spatial light modulator, and the spatial light modulator is configured by a center are a disposed on the optical axis for passing through or reflecting the reference light with no modulation, and a spatial light modulation are a disposed around the center are a for generating the signal light by modulating the reference light in accordance with the recording information. The reference light is propagated on the optical axis, and the signal light is propagated around the reference light with spatial separation therefrom. The interference section includes an objective lens and an optical device, and the objective lens and the optical device gather the reference light at a first focal point, and the signal light at a second focal point being different from the first focal point.
