Abstract:
A method for projecting a three-dimensional image, that includes providing a first light source and a second light source. A polarizing beam splitter (PBS) is disposed adjacent the first light source and the second light source. An imaging device is adjacent the PBS. A polarization flipping element is disposed adjacent the PBS opposite the imaging device, and a mirror is disposed adjacent the polarization flipping element. A first light is emitted from the first light source. The first light is polarized such that it reflects through the PBS to a polarization flipping element. The first light passes through the polarization flipping element twice such that it will reach the surface of the imaging device. The second light is emitted from the second light source after the first light is emitted. The second light is polarized such that the light passes through the PBS to the imaging device.
