Abstract:
A method is provided for projecting a three-dimensional image. The system includes a first light source, the first light source emitting light in a first direction and a second light source emitting light in a second direction. A beam splitter device is disposed adjacent each light source and an imaging device is disposed adjacent the beam splitter device. Light from the first light source and the second light source travel a common optical path to a projector lens assembly.
