Title: Band-limited double-step Fresnel diffraction and its application to computer-generated holograms. Author: Okada N, Shimobaba T, Ichihashi Y, Oi R, Yamamoto K, Oikawa M, Kakue T, Masuda N, Ito T. Journal: Opt Express; 2013 Apr 08; 21(7):9192-7. PubMed ID: 23572007. Abstract: Double-step Fresnel diffraction (DSF) is an efficient diffraction calculation in terms of the amount of usage memory and calculation time. This paper describes band-limited DSF, which will be useful for large computer-generated holograms (CGHs) and gigapixel digital holography, mitigating the aliasing noise of the DSF. As the application, we demonstrate a CGH generation with nearly 8K × 4K pixels from texture and depth maps of a three-dimensional scene captured by a depth camera.[Abstract] [Full Text] [Related] [New Search]
