Abstract
A fiber optic display apparatus consists of a plurality of optical fibers which convey a projected image from an input, or first surface, to a display, or second surface, whose area is greater than or equal to that of the first surface, such that any image projected on to the first surface appears enlarged on the second surface. The second surface is comprised of tiles which attach to adjoining tiles by means of flexible tabs and pliable locator rods in such a fashion as to allow the second surface to follow general contours (e.g. concave or convex), while the optical fiber bundles from each tile are collected into a fixture to form the first planar surface. Because of the modular design of the display it can be assembled or disassembled rapidly. A light-diffusing thin sheet or film is applied to the front of each tile of the second surface to effectively increase the numerical aperture of each fiber, thus producing a uniform wide-angle distribution of light from each fiber end and enabling viewing from any angle in front of the display.
