Complex Field Analysis of Temporal and Spatial Techniques in Digital Holographic Interferometry
… to process the digital holographic interference phase maps in complex field is proposed. Based on this concept, three temporal phase retrieval algorithms and one spatial retrieval approach are developed. Temporal complex phasor method is highly immune to noise and allows accurate measurement of …

Double Alternating Minimization (DAM) for Phase Retrieval in the Presence of Poisson Noise and Pixelation
… can only read intensity information, and thus phase information of wavefronts is lost. Phase retrieval algorithms are used to estimate the lost phase and reconstruct an accurate effective pupil function, where the squared modulus of its Fourier transform is detected by a camera. However, …

Physical Designs in Artificial Neural Imaging
… is not only taking place of the conventional algorithms, but also embracing radical and physically plausible forward models that better sample the high dimensional light field. Physical designs of sampling in turn tailor simulation and neural algorithms for optimal inverse estimation. …

Computational high-throughput phase imaging
Quantitative phase imaging (QPI) is a remarkable modality for its wide range of potentials in studying biological structures without exogenous labeling. QPI utilizes the optical phase delay across the sample, instead of the image intensity, as the image contrast mechanism to provide highly …

Improving Image Quality in Holographic Projections through Novel Iterative Algorithmic Solutions
… capable of modulating either the amplitude or phase of light, or its subpar image quality, have delayed its introduction and success in the mass market. This work focuses on the latter problem, finding novel algorithmic mechanisms for improving the image quality in replay fields. Given the …
