Title: Mantis shrimp–inspired organic photodetector for simultaneous hyperspectral and polarimetric imaging-enabling advanced single-pixel architectures
Abstract: Many spectral and polarimetric cameras implement complex spatial, temporal, and spectral re-mapping strategies to measure a signal within a given use-case’s specifications and error tolerances. This re-mapping results in a complex tradespace that is challenging to navigate; a tradespace driven, in part, by the limited degrees of freedom available in inorganic detector technology. This presentation overviews a new kind of organic detector and pixel architecture that enables single-pixel tandem detection of both spectrum and polarization. By using organic detectors’ semitransparency and intrinsic anisotropy, the detector minimizes spatial and temporal resolution tradeoffs while showcasing thin-film polarization control strategies.
Bio: Dr. Kudenov obtained his BS in Electrical Engineering from the University of Alaska Fairbanks in 2005 and his PhD in Optical Sciences from the University of Arizona in 2009. He is currently an Associate Professor in Electrical and Computer Engineering at North Carolina State University in Raleigh, NC, where he runs the Optical Sensing Lab (https://research.ece.ncsu.edu/osl/). His research interests focus on use-inspired imaging spectrometer and polarimeter sensors (UV to IR) for applications spanning agriculture, plant phenotyping (http://www.sweetpotatoanalytics.com), biomining and remediation, and quality control. He also serves as the academic advisor for the NC State SPIE student chapter.
