Computer generated holograms (CGHs) and diffractive optical elements (DOEs) have become increasingly important in lens fabrication, artificial intelligence, optical computing research, and in other applications where diffraction based optical manipulation is required. Research in these areas has been hampered by the lack of an affordable and practical system capable of printing large format, high resolution diffractive optical elements. We describe a new design for a DOE printer, based on a modified step-and-repeat printing method, which reduces these problems.
