Title: Projection type 3D display using spinning screen (SD&A 099)

Speaker: Hiroki Hayakawa, Nagaoka University of Technology (Japan)

Abstract: 3D display is effective for use in advertising and exhibition because they can attract notice. When used for advertising, 3D display demands large screen that multiple people can observe with the naked eye. Previous studies have proposed large screen 3D display using multiple projectors. However, it has difficulty in installing a large number of projectors. On the other hand, 3D display by using time-division projection has been proposed. This method displays 3D image on large screen with single high-speed projector. This display scans the reflection direction of projection image by swinging screen. However, this display has a problem of the displayed image flicker due to vibration screen. The purpose of this study is to realize large screen 3D display without flicker using single high-speed projector. In previous research, scanning speed could not be increased due to vibration screen. Therefore, we propose a new screen structure that enables high-speed scanning by reducing vibration. The proposed method consists of single high-speed projector and an array of spinning square bars. We performed computer simulation to confirm the principle. We confirmed that images with appropriate parallax can be displayed.
