Abstract
Apparatus for expanding a visual image consisting of a ribbon of clad optical fibers locked in closely-spaced, parallel relationship and cut across at a narrow acute angle at one end, the surface thus exposed being roughened in texture and the exterior of each fiber being provided in that area with a reflective material. Alternately to roughening the surface, the core of each fiber is partially etched out, and a plug of light-diffusing material inserted. A reflective layer is applied between this plug and the cladding of the fiber.
