Research Summary:

The research of the Smart Imaging Laboratory is focused on the development of novel imaging/sensing tools to tackle measurement problems in biology, medicine, and metrology. The major techniques that are under development include gigapixel microscopy platforms, super-resolution florescence imaging approaches, 3D tomography imaging, ePetri dish and related lab-on-a-chip platforms, surface-plasmon-enabled imaging devices, and other novel imaging techniques. In particular, the Fourier Ptychography approach developed by our group represents a new way of tackling microscopy by transforming a physical optical problem to a computational problem. Through this reduction, we can push the performance of standard imaging systems beyond their physical limitations. We have demonstrated the use of Fourier ptychography for high-resolution gigapixel imaging, quantitative phase imaging, spectral multiplexing, adaptive imaging, super-resolution fluorescence imaging, 3D holographic imaging, incoherent photographic imaging, and remote sensing.
