ABSTRACT:
A fiber optic writing head delivers light from the ends of a close-packed array of optical fibers through a small inexpensive lens which images the light onto the writing surface. The ends of the individual fibers in the array are fixed at various angular positions to form a surface that is the image of the writing surface through the lens. The ends of the fibers are spaced along the surface so that the image that is produced on the writing surface has uniform spacing. The angular positions of the fibers are chosen such that the axis of the refracted beam emitted by each fiber is directed at the center of the entrance pupil of the lens.
