报告题目Fourier ptychographic imaging (傅里叶叠层成像)

Abstract:

Fourier ptychography (FP) is a recently developed phase retrieval approach for large field-of-view and high-resolution imaging. This technique stitches together many variably illuminated, low-resolution measurements in the Fourier space to expand the frequency passband and recover the high-resolution complex object image. Without involving any mechanical scanning, it facilitates large field of view imaging in a simple and robust manner. In this talk, I will discuss the principle of the FP approach and its applications in gigapixel microscopy, quantitative phase imaging, 3D holographic imaging, long-range macroscopic imaging. I will also discuss how to model the Fourier ptychographic imaging process using a neural network and the extension of the FP approach for incoherent imaging settings. The FP innovation may provide new insights for the development of high-resolution imaging platforms using photon, X-ray, and electron.

Biography:

Dr. Guoan Zheng received the M.S. and Ph.D. degrees in electrical engineering from Caltech in 2008 and 2013, respectively. He is currently an assistant professor at the University of Connecticut, with a joint appointment in Biomedical Engineering and Electrical Engineering departments. He is the recipient of UConn research excellence award, Caltech Demetriades Thesis Prize, and Lemelson-MIT Caltech Student Prize. The Fourier ptychography approach developed by him and his colleagues is now a sub-chapter in Goodman’s famous textbook, “Introduction to Fourier Optics”. His current research interest focuses on the development of novel imaging and sensing techniques for biomedical applications.
