Abstract:
A method for selectively exposing a light pattern to a photosensitive work surface of a work material, said method comprising the steps of:a. providing a substrate having an elongated aperture formed therein, the substrate generally lying in plane; b. providing beam of light that can be directed generally toward the elongated aperture; c. supporting a plurality of shutter elements upon the substrate, each of the shutter elements being movable between a first position covering a portion of the elongated aperture and a second position exposing a portion of the elongated aperture, each of the shutter elements extending generally parallel to the plane of the substrate whether in the first position or second position; d. moving each of the shutter elements to either it first position or its second position to selectively block or pass portions of the beam of light in order to create a first patterned light beam exiting the elongated aperture of the substrate; e. directing the beam of light toward the elongated aperture for generating the first patterned light beam; and f. directing the first patterned light beam upon a first portion of the photosensitive work surface of the work material.
