Article
Full-text available
A novel method of correcting the aberrations of holographic projectors is presented. The method employs an optimization algorithm to determine an aberration-correcting phase mask composed of 13 Zernike Polynomials. The mask can be used thereafter to correct every image produced by the projector. Two optimization algorithms are demonstrated: a hybri...
Article
Full-text available
A method of generating an aberration- and distortion-free wide-angle holographically projected image in real time is presented. The target projector is first calibrated using an automated adaptive-optical mechanism. The calibration parameters are then fed into the hologram generation program, which applies a novel piece-wise aberration correction a...
Thesis
Full-text available
This work builds up on the greatest minds of Cambridge Holography: Adrian Cable, Edward Buckley, Jonathan Freeman, and Christoph Bay. Cable and Buckley, developed an OSPR algorithm which was the first to provide high-quality real-time hologram generation using general-purpose hardware while Freeman designed a method to correct arbitrary aberrations...
Article
This paper details the world's first live 3D holographic (diffractive) video call using off‐the‐shelf hardware. We introduce a novel pipeline that facilitates the capture, processing, and transmission of RGBZ data, using an iPhone for image and depth capture with VividQ's SDK for hologram generation and hardware for display.
Article
Full-text available
Understanding and improving the perceived quality of reconstructed images is key to developing computer-generated holography algorithms for high-fidelity holographic displays. However, current algorithms are typically optimized using mean squared error, which is widely criticized for its poor correlation with perceptual quality. In our work, we pre...
Article
Full-text available
The Cimmino algorithm is an iterative algorithm used for solving linear equations (Ax=b) and is a part of wider family of algebraic reconstruction algorithms. Despite being used in computed tomography and digital signal processing, we present an approach for using it in holographic projections in the Fraunhofer region. Following the work carried ou...
Article
Achieving the luminance of real‐world scenes is a challenge for many display technologies. Computer‐generated holography offers a number of advantages, due to both the high optical efficiency and the ability to redistribute available luminous flux to individual points. This is important while displaying sparse content that needs to be clearly perce...
Conference Paper
Full-text available
Augmented and Mixed Reality promises another leap forward in productivity and lifestyle, offering benefits with a magnitude and impact matching that of the introduction of smartphones. However, to enable this, many significant technical challenges must be overcome. Here we review the state of the art, identifying key challenges established in the l...

Article
A novel algorithm for constructing computer-generated holograms using point clusters is presented. This method exploits the precalculated triangular meshes used in previous research and can reconstruct less noisy 3D objects. In addition, the high-speed property of a ferroelectric liquid crystal spatial light modulator is utilized to enhance the rec...
Article
Full-text available
A new method for constructing computer-generated holograms using a precalculated triangular mesh is presented. The speed of calculation can be increased dramatically by exploiting both the precalculated base triangle and GPU parallel computing. Unlike algorithms using point-based sources, this method can reconstruct a more vivid 3D object instead o...
