报告题目:Recent Advances on Quantitative Phase Microscopy for Biomedical Imaging and Material Metrology

报告人:周仁杰教授


报告摘要:

Quantitative phase microscopy (QPM) is a label-free imaging technique, which has been widely applied to biomedical imaging and material metrology. In this talk, I will highlight several recent advances in QPM and their demonstrated applications from our group. I will first introduce our development of high spatiotemporal resolution synthetic aperture phase microscopy that can image and quantify millisecond-level fluctuations in living cells. I will further show our work on high-speed tomographic phase microscopy and its applications on high-speed three-dimensional (3D) cell imaging and characterization of 3D-printed structures. After that, I will talk about our recent work on single-frame label-free cell tomography with an unprecedented speed of >10,000 volumes/second. Then, I will move to our work on correlating the phase maps with clinically-relevant information with machine learning with an example on classifying leukocyte subtypes, which has achieved over 90% classification accuracy without using chemical reagents with cross-validation on human blood donors. Finally, I will present our results on pushing the phase sensitivity limit to ~2 picometers, which has laid the foundation to develop quantitative phase profilometry for mapping the thickness maps of 2D materials. To further demonstrate the potential of our QPM platforms, we are open to more research collaborations in the future.
