초록 ▼

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.

A fiber optic projection system, comprising: a housing; a light source mounted within the housing; a multiple color wheel mounted in the housing having a plurality of irregularly shaped colored regions having a smallest cross-sectional dimension; a fiber optic bundle held in a cylindrical shape and having a plurality of optical fibers of substantially uniform cross-sectional dimension, forming an input end and an output end fixed in the housing, the fiber optic bundle including 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, wherein the fiber optic groups are of variable size, with the smallest of such groups having a smallest cross-sectional dimension; wherein the multiple color wheel is mounted between the light source and the input end of the fiber optic bundle; wherein the smallest cross-sectional dimension of the smallest fiber optic group is not less than the smallest cross-sectional dimension of the smallest colored region, and the smallest cross-sectional dimension of the smallest colored region is not less than the cross-sectional dimension of the fibers; a first motor for rotating the color wheel; a second motor for reciprocating the color wheel laterally with respect to the longitudinal axis of the fiber optic bundle; and a projection lens for receiving light from the fiber optic bundle\s output end and imaging the light at a remote location.
