DOI: 10.1109/tci.2025.3622992
Abstract: We introduce a probabilistic approach to ptychographic reconstruction in computational imaging. Ptychography is an imaging method where the complex amplitude of an object is estimated from a sequence of diffraction measurements. We formulate this reconstruction… read more here.

DOI: 10.1364/ao.452835
Abstract: Near field ptychography uses diffraction data collected at large Fresnel numbers, together with iterative reconstruction algorithms, to realize quantitative phase imaging of transmissive samples. It delivers excellent phase sensitivity with a wide field of view… read more here.
