    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 display system includes assemblies or subsystems each adapted to combine holographic displays and coarse integral displays to produce or display a coarse integral hologram. The display system is adapted to combine such displays or display systems to add more detail or information. For example, the display system can be assembled as if it were made up of “holographic bricks” that can be stacked and combined to provide a unique image/output. Briefly, the display system described herein teaches techniques for combining coarse integral holographic (CIH) displays in a seamless and scalable manner, e.g., a display system where multiple spatial light modulators (SLMs) can be placed or provided behind coarse integral optics.

    摘要: A holographic reproducing apparatus includes: a photorefractive crystal configured to have holographic images recorded in a plurality of different angles respectively; and a light source configured to supply a plurality of reproducing light beams to be incident to the photorefractive crystal in different angles, wherein the reproducing light beams have a same frequency and a same optical length as a reference light beam used when the holographic images are formed. In the holographic reproducing apparatus, each of the holographic images can be presented in different angles without interference therebetween, so that observers in a plurality of orientations can view the holographic images recorded in the photorefractive crystal, thus the problem that the viewing angle is unique in the holographic reproducing procedure is addressed.

    摘要: An electronic holographic display device includes: a beam emitting device; a plurality of polarizing beam splitters; a plurality of spatial light modulators, each of which is disposed with prescribed distances therebetween and modulates a beam vertically made incident from the corresponding polarizing beam splitter; a magnifying optical system; and a reducing optical system. The magnifying optical system includes a first lens array and a second lens array. The reducing optical system includes a third lens array and a fourth lens array. A distance “a” between the spatial light modulator and the first lens is represented by a=(k+2)f0/(k+1), wherein a ratio “k” is a distance between two adjacent spatial light modulators, to a size of the spatial light modulator, and f0 is a focal point distance of the first lens.
