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…
Variance and Error in One-Step Phase-Retrieval
Peter J. Christopher, Timothy D. Wilkinson
Time multiplexed approaches for high frame-rate holographic displays have been around since the invention of One-Step Phase-Retrieval (OSPR) in the early 2000s. When discovered, fo…
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…
Grayscale-to-color: Single-step fabrication of bespoke multispectral filter arrays
Calum Williams, George S. D. Gordon, Sophia Gruber +2
Conventional cameras, such as in smartphones, capture wideband red, green and blue (RGB) spectral components, replicating human vision. Multispectral imaging (MSI) captures spatial…
