Development of Time-Multiplexed Autostereoscopic Display Based on LCD Panel

The main advantage of time-multiplexed stereoscopic display is that high-resolution stereoscopic images can be displayed using single monitor. In a time-multiplexed stereoscopic system left and right images of a stereopair consequently appear on the screen of 2-D display. The viewer is able to see the left and right images separately due to special shutter glasses or passive polarized eyeglasses combined with a polarization switch, sequentially occluding the left and the right eyes, thus preventing the viewer’s eyes from seeing wrong images. Since conventional 2-D images and components of the stereopair may be displayed with the same full resolution of the image panel, 2-D / 3-D switching of the display is potentially unnecessary. Both 3-D and 2-D content can be displayed on the same screen simultaneously. Time-multiplexed stereoscopic systems, utilizing polarization shutter glasses and polarization switchable screens are well-known and have been the objective of much research [1,2,3,4,5]. The shutter glasses system has two wearable optical switches, capable of switching their transparency thus blocking the left or right eye. The passive polarized eyeglasses system has one large (screen size) optical polarization switch switchable between two

Projection-type integral 3D imaging using multifacet flat mirrors

We propose a projection-type integral imaging scheme using multi-facet flat mirrors and demonstrate its feasibility. Instead of spherical mirrors on a flat surface, multi-facet flat mirrors which contacts with the tangential line of a curved surface function like elemental mirror component. Lights reflected from different facet of each mirrors give different viewing perspectives. By using electronic capturing and display devices, the proposed method makes it possible to record and reconstruct 3D scene in real-time. In the experiment, only horizontal parallax is provided because one-dimensional surface can be made more easily. But extension for two-dimensional or computer generation of elemental images can also be done.
