摘要: An exemplary embodiment of the present invention provides a diffractive photo-mask comprising body element, plurality interference/image-forming hologram gratings, and zero-order beam blocking element. The gratings can be located on or in are configured to diffract light produce one more functional elements surrounded by high-spatial-frequency periodic optical-intensity distribution at substrate plane when is incident upon photo-mask. element block diffracted beams
