Using Commodity Graphics Hardware for Real-Time Digital Hologram View-Reconstruction

Lukas Ahrenberg, Andrew J. Page, Bryan M. Hennelly, John B. McDonald and Thomas J. Naughton, Journal of Display Technology, Accepted for publication, 2008. Abstract: View-reconstruction and display is an important part of many applications in digital holography such as computer vision and microscopy. Thus far, this has been an offline procedure for megapixel sized holograms. [...]

Computer Generated Holograms from 3D Meshes using an Analytic Light Transport Model

Lukas Ahrenberg, Philip Benzie, Marcus Magnor, and John Watson, Applied Optics, Vol. 47, No. 9 Abstract: We present a method to analytically compute the light distribution of triangles directly in frequency space. This allows for fast evaluation, shading, and propagation of light from 3D mesh objects using angular spectrum methods. The algorithm complexity is only [...]

Computer generated holography using parallel commodity graphics hardware

Lukas Ahrenberg, Philip Benzie, Marcus Magnor and John Watson, Optics Express vol. 14, issue 17. August 2006. Abstract: This paper presents a novel method for using programmable graphics hardware to generate fringe patterns for SLM-based holographic displays. The algorithm is designed to take the programming constraints imposed by the graphics hardware pipeline model into consideration, [...]
