Abstract

We present a special-purpose computer named HORN (HOlographic ReconstructioN) for fast calculation of computer- generated holograms (CGHs). The HORN can realize parallel processing of the CGH calculation by using field- programmable gate arrays. The latest version of HORNs, HORN-7, can reconstruct holographic images more clearly than previous HORNs because HORN-7 can make CGHs as a phase-only hologram (kinoform). In addition, the HORN- 7 can directly output calculated CGHs on a spatial-light modulator via Digital Visual Interface. In this paper, we demonstrate real-time reconstruction of holographic motion pictures by the HORN-7. We calculated CGHs, which consist of 1,920 × 1,080 pixels, from the object data of ~6,000 points, and succeeded in reconstructing holographic motion pictures from the calculated CGHs at the rate of ~7 frames per second.
