Recently, various light-field displays with special structures have been suggested. Among them, the cylinder-shaped display has distinct advantages in providing 360-degree field of view. In this paper, we propose a cylindrical light-field display which consists of panoramic projection optics and a cylindrical screen with several long vertical narrow openings. The projected scene is imaged on the inner surface of the cylinder and the contents are watched through the slit on the side of the cylinder during it rotates. Therefore, horizontal-parallax-only light field is formed to display threedimensional contents inside of the cylinder.
Recently, super multi-view technology has been considered as one of the most popular research topic and many studies
have been done to improve the quality of such super multi-view display. In this paper, we present specific experiments
for human cognition. We designed our system for the special purpose that the human cognition of 3D contents is
examined. In comparison of the previous super multi-view displays, the number of views in our system can be
controlled. Our system has a great advantage that the effect of the number of views can be evaluated at the common
system. We can change the number of views, by changing the synchronization ratio which determines the speed of the
opening of the optical chopper and the refresh time of the DMD. We expect that this system will be useful for
understanding the principle of the human cognition for 3D display.
Three-dimensional (3D) display usually provides binocular disparity to observer. To construct 360degree table-top display, lots of views are required. In order to display a large amount of views to observer, time-multiplexing technique is applied. We suggest a new structure for view-sequential 360-degree table-top display system. In my system, a transmissive screen is used and digital micromirror device (DMD) image is projected on it. This system defines the direction of bundle of rays to configure the sequential view. It has some advantages resulting from the transmissive flat screen. When the transmissive screen is used instead of the reflective one, the light power efficiency is improved. Moreover, the arrangement of the pixel is more uniform when the screen is flat instead of a static conic screen. We construct a table-top display with about 288views around 360degree and its feasibilities are confirmed.
