Abstract:
An apparatus for projecting a tiled image in an aircraft cockpit comprising:a plurality of lamps for generating light; a plurality of adjacent display surfaces each having a display surface image viewing area thereon, with a projector side and a viewing side; a plurality of electro-optical light modulating devices, which are each optically coupled to at least two of said plurality of lamps and electrically coupled to and responsive to signals from sensors on an aircraft, said electro-optical light modulating devices generate images having a predetermined modulating device image size; a lens disposed between said electro-optical light modulating devices and said projector sides of said display surfaces for causing an enlargement of said images from said predetermined modulating device image size to a size of said display surface image viewing area; a viewable image is caused to be formed on said viewing side of said display surface in response to light which is generated by said plurality of lamps, modulated by said electro-optical modulating device, and enlarged by said lens; a first polarizing beam splitting prism and a second polarizing beam splitting prism disposed between said plurality of lamps and said plurality of electro-optical light modulating devices; and, said first polarizing beam splitting prism and said second polarizing beam splitting prism adapted and configured for sharing linearly polarized light for use on adjacent electro-optical light modulating devices in said plurality of electro-optical light modulating devices.
