Abstract: A fiber optic display includes an array of optical fibers arranged in a matrix having multiple rows, each row having multiple discrete optical fibers. The output ends of the fibers are held in precise registration by a set of spacers. Each spacer defines an array of parallel grooves on one side, and each groove is sized to receive a single respective one of the optical fibers. Each of the grooves is separated by a land having a width, and the optical fibers in each row are laterally separated from one another by a distance no less than the width of the land. The optical fibers are secured in the grooves with no more than one optical fiber in each groove such that the grooves position the optical fibers precisely with respect to one another within each row. The spacers are secured together in aligned registration to form a display surface aligned with the light output ends of the optical fibers, and this display surface is positioned at an acute angle with respect to the grooves.
