Polarization Microscope for Live Imaging

Polarization, a fundamental feature of light, is a useful parameter in understanding the complex optical responses of matter and unraveling unique properties that are otherwise missing. Usually, quantitative polarization imaging demands multiple measurements, which is inappropriate in various practical situations. In this webinar, Rakesh Kumar Singh will discuss and present some of his recent work on the development of polarization microscopy for spatially resolved and label-free imaging. The presentation will emphasize holographic microscopy for single-shot polarization imaging, and its possible applications in the characterization of soft matter and biological samples.
