超高精細空間光変調器を用いた電子ホ口グラフィ3次元映像システム

摘要

Since electronic holography has the potential to display natural 3D motion images of the highest quality, it is expected to be the future's ultimate 3D video system. However, many difficult problems remain before such a practical system can be realized. The principle and the advantages of 3D image display by holography and the realization problems of an electronic holography video system are reviewed. The viewing-zone angle and display size problems are crucial. To solve those problems, NICT has recently developed an experimental electronic holography 3D display system with ultra high definition display devices as spatial light modulators and enlargement technology of the viewing-zone angle. The system has a wide 15 ° viewing-zone angle and a 4-cm-diagonal display size. These performances are currently the state of the art in electronic holography. Finally, we describe some future prospects for electronic holography.
