Research

research overview

  • 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.

Teaching

courses taught

  • ECEN 5126 - Computational Optical Imaging
    Primary Instructor - Spring 2018 / Spring 2019
    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
    Primary Instructor - Fall 2019
    Covers the application of Maxwell's equations to optical wave propagation in free space and in media.Topics include polarization, dispersion, geometrical optics, interference, partial coherence, and diffraction. Recommended prerequisite: ECEN 3410.
  • ECEN 5696 - Fourier Optics
    Primary Instructor - Fall 2018
    Introduces a system level approach to the analysis and design of optical systems. Topics include holography, Fourier transform properties of lenses, two-dimensional convolution and correlation functions, spatial filtering and optical computing techniques. Also covers coherent and incoherent imaging techniques, tomography, and synthetic aperture imaging. Recommended prerequisites: ECEN 3300 and ECEN 3410.
