Transmission and Reconstructed of the Computer Generated Hologram using the Digital Wireless LED Visible Light Communication ― Improvement of the reconstruction image using the band pass filter ―

Abstract

In the case of a hologram displaying three dimensions, reconstruction illumination light is necessary to visualize it. In other words, the use of the visible light that transmission and the reconstruction of the hologram are possible is effective. However, the use in infrared rays of an electric wave and the IrDA (Infrared Data Association) of the conventional communication was hard to reconstructed. Therefore we reduced influence of the dispersion using a narrow band pass filter of the half bandwidth and improved the reconstruction image. After having carried out activity, we applied a visible light device to an IrSimple technology and examined possibility of the visible light communication. Thus, we apply IrSimple protocol to a visible light technology and report it in the transmission of the computer composition hologram and the one which reconstructed.
