Abstract: A hologram generation apparatus is based on a hologram imaging system which includes an object space where an object is situated and a retina space or region where an image is formed within an eyeball of an observer. The hologram generation apparatus includes a modeling unit for generating first graphic data by transforming a 3D image of a 3D object to a set of polygonal facets; a data transformation unit for generating second graphic data by transforming the first graphic data from the modeling unit to normal/reference coordinates in the retina region; a hologram generation unit for generating a first computer generated hologram (CGH1), which is light wave analysis data for the second graphic data; and a hologram transformation unit for transforming the first computer generated hologram (CGH1) in the retina region to a second computer generated hologram (CGH2) in the object space.

Abstract: A broadband light absorber and a display apparatus including the same. The broadband light absorber includes a substrate and a pattern layer having a mesh structure including a plurality of openings, wherein any neighboring openings among the plurality of openings are non-uniform and wherein the plurality of openings comprise first openings haying a first size and second openings haying a second size different from the first size, the first openings and the second openings being alternately arranged in a first direction.
