Abstract

A system for performing digital lithography onto a subject is provided. The system includes a noncoherent light source for producing a first light and an optical diffraction element for individually focusing the first light into a plurality of second lights. The system also includes a pixel panel for generating a digital pattern, the pixel panel having a plurality of pixels corresponding to the plurality of second lights. A lens system may then direct the digital pattern to the subject, thereby enabling the lithography.
