Defocused images removal of axial overlapping scattering particles by using three-dimensional nonlinear diffusion based on digital holography
Wei-Na Li, Zhengyun Zhang, Jianshe Ma +2
We propose a three-dimensional nonlinear diffusion method to implement the similar autofocusing function of multiple micro-objects and simultaneously remove the defocused images, w…

Coherence retrieval using trace regularization
Chenglong Bao, George Barbastathis, Hui Ji +2
The mutual intensity and its equivalent phase-space representations quantify an optical field's state of coherence and are important tools in the study of light propagation and dyn…

Superfast maximum likelihood reconstruction for quantum tomography
Jiangwei Shang, Zhengyun Zhang, Hui Khoon Ng
Conventional methods for computing maximum-likelihood estimators (MLE) often converge slowly in practical situations, leading to a search for simplifying methods that rely on addit…
