<p>A method is disclosed for making a fiber optic array for use in an optical scanning device. The array (10) includes a substrate (16) and a plurality of optical fibers (12) arranged on the substrate (16) to form a linear array of the fibers (12). Each of the fibers (12) is received in grooves (28a-28g) formed in the substrate (16) to precisely space the fibers relative to each other. Each fiber (12) is adapted to receive light from a source (22) such as a laser diode. In order to increase the packing density of the fibers (12) in the array, the fibers are closely spaced relative to each other on the substrate (16). The fibers (12) are arranged in aligned sets of grooves (28a-28g) which are spaced apart by planar areas (29a-29f) on the substrate, and the pitch (p) of the grooves (28a-28g) in successive sets decreases as the fibers (12) approach an output end (17) of the array to draw the fibers closer together at this end.</p> |
