Quantitative phase imaging (QPI) applied to holographic microscopy harnesses coherent light interference to record both intensity and phase information, enabling label-free visualisation of ...

Quantitative phase imaging is a powerful, non-invasive and quantitative microscopy technique that allows multi-scale imaging of cellular systems, explain Mustafa Mir and Gabriel Popescu Imaging by ...

Image of the Day: Membrane Map The membranes of red blood cells stored in blood banks lose flexibility over time; scientists at the University of Illinois at Urbana-Champaign detected these membrane ...

Using spatial light interference microscopy (SLIM) techniques developed by Gabriel Popescu, director of the lab, the researchers were able to show for the first time how human embryonic stem cell ...
