Time-multiplexed light field display with 120-degree wide viewing angle

Integral Imaging Three-dimensional (3d) Display with Wide-viewing Angle Using Multiple Illuminations

In this paper, a three-dimensional (3-D) integral imaging (II) system to improve the viewing angle by using the multiple illuminations is proposed. In this system, three collimated illuminations that are directed to three different angles in order to get widen propagation angle of point light source (PLS). Among three illuminations two slanted illuminations increase the propagation angle of PLS...

Real-Time Warps for Improved Wide-Angle Viewing

Providing wide angle views is often advantageous to provide context, such as in video conferencing, or when viewing panoramic imagery. Unfortunately, wide angle images often appear distorted. The limited image size on monitors or paper together with standard viewing distances, results in the angle subtended by the image when viewed usually being much smaller than the field of view of the camera...

Time - multiplexed color autostereoscopic display

A practical color autostereoscopic display has been developed at Cambridge, and has been in operation since 1994. It provides six view directions at half VGA resolution (640 × 240 pixels) of 24-bit color at a luminance of 100 cd/m2. Each individual view direction is refreshed at standard television rates, so the display is capable of full motion animation or live 3D video. Versions with both 10...

Wide viewing angle dynamic holographic stereogram with a curved array of spatial light modulators.

A novel design of dynamic holographic stereogram with a curved array of spatial light modulators (SLMs) is proposed. In general, it is difficult to simultaneously achieve a wide viewing angle and an available width for the digital holographic display. Moreover, the wide viewing angle of a display system needs a large optical numerical aperture where the paraxial approximation fails, and thus an...
