Abstract
Official abstract text for this publication.
A system is provided projecting a three-dimensional image. The system includes a first light source, the first light source emitting light in a first direction. A second light source is provided, the second light source emitting light in a second direction, the second direction being opposite the first direction. A beam splitter device is disposed between the first light source and the second light source to receive light from the first light source and the second light source, the beam splitter device being arranged to rotate about an axis. An LCoS image device is disposed adjacent the beam splitter device, the LCoS image device having an image surface arranged substantially perpendicular to the first direction and the second direction.
