| 摘要 |
A system for projecting to a viewing surface including an illumination source to project a first image onto the viewing surface along a beam path, a focusing system to focus the first image, provided in a first polarization state and projected from the illumination source, at a first image plane along the beam path between the illumination source and the viewing surface, a transmissive LCD, through which the first image is transmitted, for placement in the beam path at the first image plane with the LCD further configured to propagate a second image, provided in a second polarization state, and a first polarized filter configured to provide the first image in the first polarization state before the first image is transmitted through the LCD. At least one of the first image and the second image is in a non-detectable polarization state when illuminated upon the viewing surface. |
