Color three-dimensional display with omnidirectional view based on a light-emitting diode projector.
A three-dimensional (3D) color display with 360 degrees omnidirectional views is developed by use of a high frame rate digital micromirror device projector and three-color light-emitting diodes as the light source. The high-speed projector can project a series of color images on a rotating anisotropic diffusing mirror that controls the reflective light in a designed angular region. Observers around the display scene can watch autostereoscopic views from the ominidirectional 360 deg view around the 3D display. The vivid 3D scene can be obtained with perfect color effect and correct parallax, projection effect, and occlusion. The principle of the omnidirectional view 3D color display is analyzed in detail and experimental results of a 3D color object are presented.
