ABSTRACT:
A lens comprising a plurality of identical straight optical fibers arranged in a bundle with at least a portion of each fiber treated to suppress internal reflections, so that each fiber transmits only rays which enter the end of the fiber substantially parallel to its axis at that point, the angle between adjacent fibers of the bundle of optical fibers being adjustable to provide a lens for a range of solid angles, with a field of any shape and an image adjustable in size which may be altered in location and plane, by extending the optical fibers by flexible sections with internal reflections permitting transmission of rays on curved paths.
