Single-shot Fourier ptychography using polarization-encoded illumination

Hansol Yoon, Hyesuk Chae, Kyung Chul Lee, Kyungwon Lee et autres

Fourier ptychography (FP) is widely adopted for label-free, high-resolution quantitative phase imaging (QPI) of biological samples. However, its imaging speed is limited by the need for multiple acquisitions. In this work, we propose a single-shot FP technique that uses linear polarizers to …

Restoring H&E stain in faded slides via phase-to-color virtual staining in near-infrared

Hyesuk Chae, J. H. Kim, Joonsung Jeon, Kyungwon Lee et autres

Histological stains, such as hematoxylin and eosin, tend to fade over time, compromising subsequent analysis accuracy. Traditional methods of restoring stain color in faded samples involve physical re-staining, which is time-consuming and expensive and may damage tissue samples. In addition, digital post-processing …
