Digital holographic display with a two-dimensional (2D) and three-dimensional (3D) convertible feature is proposed. The 2D and 3D convertible feature is implemented by a high speed switchable diffuser. In a 3D display mode, 3D images are displayed by the principle of the digital holography with a coherent surface light source. An electrically controlled switchable diffuser changes the coherent light into a scattered surface light to display 2D images in a 2D display mode. The displayed image on a spatial light modulator for 2D and 3D display modes is in synchronizes with the status of the diffuser, diffuse or clear, which is electrically controlled by a personal computer. The experimental results show that the proposed method is capable of displaying 2D images and 3D digital hologram convertibly.

More about this publication?
  • 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.
