Linear time algorithm for phase sensitive holography
Peter J. Christopher, Ralf Mouthaan, Miguel El Guendy +1
Holographic search algorithms such as direct search and simulated annealing allow high-quality holograms to be generated at the expense of long execution times. This is due to sing…
Improving performance of single-pass real-time holographic projection
Peter J. Christopher, Ralf Mouthaan, Vamsee Bheemireddy +1
This work describes a novel approach to time-multiplexed holographic projection on binary phase devices. Unlike other time-multiplexed algorithms where each frame is the inverse tr…
Holographic Predictive Search: Extending the Scope
Peter J. Christopher, Ralf Mouthaan, George S. D. Gordon +1
Holographic Predictive Search (HPS) is a novel approach to search-based hologram generation that uses a mathematical understanding of the optical transforms to make informed optimi…
Sympathetic quantisation -- a new approach to hologram quantisation
Peter J. Christopher, Ralf Mouthaan, A. Mohamed Soliman +1
Spatial light modulators can typically only modulate the phase or the amplitude of an incident wavefront, with only a limited number of discrete values available. This is often acc…
Improving pixel differentiation in holographic images
Peter J. Christopher, Ralf Mouthaan, John P. Freeman +1
Computer generated holography (CGH) has seen a resurgence in recent years due, in part, to the rise of virtual and mixed reality systems. The majority of approaches for CGH are bas…
Characterising optical fibre transmission matrices using metasurface reflector stacks for lensless imaging without distal access
George S. D. Gordon, Milana Gataric, Alberto Gil C. P. Ramos +5
The ability to form images through hair-thin optical fibres promises to open up new applications from biomedical imaging to industrial inspection. Unfortunately, deployment has bee…
