Abstract:
A maskless exposure system for selectively exposing a work material having a photosensitive work surface to light, said maskless exposure system comprising in combination:a. a substrate having an elongated aperture formed therein, said substrate generally lying in a plane;b. a source of a light beam directed generally toward the elongated aperture;c. a plurality of shutter elements movably supported upon said substrate, each of said shutter elements having a first position covering a portion of the elongated aperture and preventing the passage of light through such portion, and each of said shutter elements having a second position exposing a portion of the elongated aperture for allowing the passage of light through such portion, each of said plurality of shutter elements extending generally parallel to the plane of said substrate, said plurality of shutter elements creating a patterned light beam exiting the elongated aperture of said substrate;d. a plurality of actuators, each of said actuators cooperating with a related one of said plurality of shutter elements for selectively moving said related shutter element between its first position and its second position;e. a work material support for supporting a work material having a photosensitive work surface; andf. a stepper for adjusting the relationship between the patterned light beam exiting the elongated aperture of said substrate and the work material support in order to direct the patterned light beam at different portions of the photosensitive work surface of the work material.
