This article describes a high resolution aerial 3D display using a time-division multiplexing directional backlight. In this system, an aerial real image is generated with a pair of large convex lenses. The directional backlight is controlled based on the detected face position so that binocular stereoscopy may be maintained for a moving observer. By use of the directional backlight, the proposed system attains autostereoscopy without any moving parts. A wide viewing zone is realized by placing a large aperture convex lens between the backlight and the LCD panel. With the advantage of time-division multiplexing, a high resolution 3D image is presented to the viewer. [DOI: 10.2352/J.ImagingSci.Technol.2015.59.6.060402]

  • For more than 30 years, the Electronic Imaging Symposium has been serving those in the broad community - from academia and industry - who work on imaging science and digital technologies. The breadth of the Symposium covers the entire imaging science ecosystem, from capture (sensors, camera) through image processing (image quality, color and appearance) to how we and our surrogate machines see and interpret images. Applications covered include augmented reality, autonomous vehicles, machine vision, data analysis, digital and mobile photography, security, virtual reality, and human vision. IS&T began sole sponsorship of the meeting in 2016. All papers presented at EIs 20+ conferences are open access.

    Please note: For purposes of its Digital Library content, IS&T defines Open Access as papers that will be downloadable in their entirety for free in perpetuity. Copyright restrictions on papers vary; see individual paper for details.
