This paper proposes an electronic version of coarse integral volumetric imaging (CIVI) display with wide viewing angle. CIVI is a 3D display solution which combines multiview techniques based on integral imaging with volumetric techniques using multilayer panels. Though CIVI has solved most of the major problems of conventional 3D displays, it still has two shortcomings to be overcome. One is the difficulty in realizing electronic display due to unavailability of electronic color display panels transparent enough to be layered for volumetric imaging. The other is the limited viewing angle because of the aberration of lenses. As for the former problem the simplest way to attain electronic version of CIVI is to use half mirrors to merge multiple images from different depths. Though high quality 3D image can be attained with this method, the system size becomes large. To avoid bulky mirror system and realize compact system size, the authors propose layered use of a color panel and multiple monochrome panels to emulate color volumetric display. To expand viewing angle, the authors propose a display system where smaller CIVI display components, each of which has little aberration, are connected so that each display plane faces toward the center of the image optically generated.© (2010) COPYRIGHT SPIE--The International Society for Optical Engineering.
