The research in Dr. Piestun's group deals with the control and processing of optical radiation at two significant spatial and temporal scales: the nanometer and the femtosecond. Interest in this area arises from the existence of new phenomena occurring at these scales and the fascinating applications in new devices and systems. Current challenges in sensing, imaging, communications, energy conversion, and computing provide a continuous motivation for this work.

ECEN 5126 - Computational Optical Imaging
Spring 2018 / Spring 2019 / Spring 2021
Covers the fundamentals of computational optical imaging modalities, namely systems in which the hardware (optics, sensors, illumination) is designed in conjunction with algorithms (implemented optically, electronically and via software) to deliver information about a scene. Students learn the analysis and design of modern imaging systems. Covers a variety of applications including biomedical imaging, nanoscopy, photography and space imaging.
ECEN 5156 - Physical Optics
