Talk Title: Design framework for a plenoptic camera using wave propagation
techniques

Talk Abstract: Plenoptic cameras are designed to capture different
combinations of light rays from a scene, sampling its light field, and
enable applications such as digital refocusing, or depth estimation. Image
formation models for such cameras are typically based on geometric optics.
Little work has been performed so far on analyzing diffraction effects and
aberrations of the optical system. We demonstrate simulation of a plenoptic
camera optical system using wave propagation analysis and show how the
diffraction effects influence performance in the case where a spectral
filter mask is inserted into the main lens.

Speaker's Biography: Kathrin Berkner is research manager of the Computation
Optics & Visual Processing Group at Ricoh Innovations, where she is
responsible for creating technology for computational imaging and sensing
systems, starting from optical and digital design to prototyping to making
the systems practical for use in commercial applications.

Before working on computational imaging systems, Kathrin developed
technologies for restoration and enhancement of images, reformatting of
documents and images to adapt to small-size displays, as well as graphical
models for structuring document information for social media. Prior to
joining Ricoh she was a Postdoctoral Researcher at Rice University, Houston,
TX. Kathrin holds a PhD. degree in mathematics from the University of
Bremen, Germany.
