ESE Seminar: "Nonlinear Optical Imaging and Spectroscopy"

Apr 24
2 p.m.
Green Hall, Room 0120

​Zhiwen Liu, Professor of Electrical Engineering at Penn State University, will present.

Abstract: Merging the capabilities of vibrational spectroscopy and holography can lead to new opportunities for bioimaging. The vibrational response of target molecules provides a means for chemical contrast, while holographic detection captures both the amplitude and the phase of a complex signal field to enable label-free three-dimensional imaging. Vibrational spectroscopic holography, including holographic coherent anti-Stokes Raman scattering imaging and holographic sum frequency generation imaging, will be discussed. The underlying principles, digital reconstruction methods, and instrumentation will be presented. In addition, our recent progress on smartphone based optical spectroscopy and its applications will also be discussed.
