Image projection device and associated method


Lamvik, M. (2003). IPC No. U.S.Image projection device and associated method (Patent No. 6520649.)


An image projection device adapted to project an image on a remotely disposed display is provided. The image projection device comprises a plurality of image elements, each image element being configured to emit an image portion therefrom. The image portions are directed through a projection lens, configured to cooperate with the image elements, and projected onto the remote display. A plurality of fiber-optic elements, corresponding to the plurality of image elements, is disposed between the image elements and the projection lens. Each fiber-optic element is configured to have a light-emitting end, toward the projection lens, tapering to a light-receiving end toward the corresponding image element. The fiber-optic element is thereby configured to receive the image portion from the image element at the light-receiving end and to expand the image portion before emitting the expanded image portion from the light-emitting end. The light-emitting ends of the fiber-optic elements are contiguously arranged so as to combine the image portions into a contiguous display image, wherein the contiguous display image is then directed through the projection lens so as to be projected onto the remote display. An associated method is also provided.
