Title:[Invited] Representation and Synthesis of Computer-Generated Holograms
Hwi Kim and Dajeong Im (Korea Univ., Korea)
Abstract: The comptuational algorithm of polygon computer-generated holograms (CGHs) is overviewed based on our recent research results and several issues related to computational algorithms are discussed. The issues are categorized into the representaton theory of three-dimensional objects with various surface textures and the efficient algorithm for the calculation of the field representation. In this talk, the texturing, backgroud insersion, and occlusion process of the polygon CGH represetation are described. The fast calculation of the CGH, even though it is approximate, is desirable if the fast approximate calculation does not significantly deteriorate the holographic image quality. Our own research results realted to this problem is introduced. The first is the reconfiguration algorithm of bandlimited wide-viewing angle CGH that is targeted to model CGH for different observation positions and the second is the accelerated fast CGH calculation exploting the sparisity property of the polygon CGH.
