“…Figure 2 compares the beam propagation directions of DMDs and other SLMs. The separation angle is very large compared with that of a typical SLM, which is less than 3.5°for a green laser beam (λ = 532 nm) [12]. Due to this large separation, the reconstructed image from a DMD is easily separated from the illuminating beam.…”

Digital micromirror device's (DMD) properties as being a display device for holographic displays are investigated. High speed, a large separation between reconstructed image and reconstruction beam, two symmetric diffraction patterns, and low intensity (0,0)th-order beam at a blazed grating condition are the desired properties for the displays. The blazed grating condition of a DMD can reconstruct images with higher diffraction efficiency than the line grating condition. DMD's high speed enables to present colors and gray levels to the reconstructed image. However, reconstructed images from a gray-level computer-generated hologram (CGH) and its binary form hologram reveal no noticeable difference between them, except the background noise in the image from the CGH.

“…As a result, the development of a spatial light modulator (SLM) with a very small pixel pitch has become extremely important in the realization of the electronic-holography images with wide viewing-zone angles. A significant amount of research activities to enlarge the viewing-zone angle has been carried out using various techniques, such as with time-alternating methods and the use of high-order diffraction [16], [17], single sideband techniques [18], and undesired light elimination techniques [19].…”

We introduce various 3D motion picture technologies, from the commercially available stereogram to a spatial image methods such as holography. We show a magneto optical spatial light modulator with sub-micron pixels driven by spin transfer switching (spin SLM) as a holography display device. It has a potential to solve the long-standing narrow viewing zone issue. We have developed the spin SLM with a transistor back plane which plays an important role for extending large scale. The fabricated spin SLM has 10 × × × × 5 pixels with magnetic tunneling junctions with backplane transistors. We have successfully demonstrated its electrical operation with as low current density as 0.6 MA/cm 2 which is one of the smallest current density with spin transfer switching, and confirmed its contrast change by magnetization switching in light modulation elements. In summary, we have shown that the Spin SLM with backplane transistor technology could be crucial technology to solve the critical issue for the electrical holography.

A color matching method for improving the color reproduction quality of color computer-generated holography (CCGH) is proposed. It is found that the amplitude of object wave in CCGH is related with object's color quantity in computer display colorimetric system, three primary wavelengths of CCGH and spectral distribution of illuminant source. Thus, this paper presents the conversion relationship between color quantity in computer display colorimetric system and amplitude of object wave in CCGH, which can improve the color quality of holographic image. In order to demonstrate the effectiveness of the proposed method, two experiments are conducted. The CCGH targets are respectively two-dimensional (2D) color object, three-dimensional (3D) gray and color mixed object. The experimental results demonstrate that the proposed color matching method of CCGH is effective. It has practical applications in both static and real-time dynamic holographic display, especially in high quality CCGH display.
