Efficient representation, generation and compression of digital holograms (2018)
Abstract / truncated to 115 words
Digital holography is a discipline of science that measures or reconstructs the wavefield of light by means of interference. The wavefield encodes three-dimensional information, which has many applications, such as interferometry, microscopy, non-destructive testing and data storage. Moreover, digital holography is emerging as a display technology. Holograms can recreate the wavefield of a 3D object, thereby reproducing all depth cues for all viewpoints, unlike current stereoscopic 3D displays. At high quality, the appearance of an object on a holographic display system becomes indistinguishable from a real one. High-quality holograms need large volumes of data to be represented, approaching resolutions of billions of pixels. For holographic videos, the data rates needed for transmitting and encoding of ... toggle 20 keywordsdigital holography – diffraction – computer generated holography – sparse transforms – holographic display – holographic imaging – data compression – wavelets – transforms – JPEG 2000 – directional transforms – wavelet packets – phase unwrapping – phase-only filters – microscopy – cell sorting – inverse problems – computational imaging – phase retrieval – time-frequency modelling
