Abstract
A projection system using a randomized fiber optic bundle for generating a wide variety of fluid visual images. A light source focusses light through a multiple color filter onto the input end of a fiber optic bundle having a plurality of optical fibers and held in a cylindrical shape. The fiber optic bundle includes a plurality of fiber optic groups that are interwoven such that the arrangement of the fiber optic groups at the fiber optic bundle's input end is different from the arrangement of the fiber optic groups at the fiber optic bundle's output end. The multiple color filter is movable such that light of time-varying color is directed into each of the optical fibers. The time-varying colored light is received by a projection lens and imaged at a target.
