Imaging Science Seminar - Hyperspectral Imaging Applications and Novel Sensor Development
Hyperspectral Imaging Applications and Novel Sensor DevelopmentDr. Julia R. DupuisVice PresidentTactical Systems, Physical Sciences, Inc.Abstract:This seminar presents an application-driven approach to novel hyperspectral imaging sensor design. Brief summaries of hyperspectral imaging modalities and their relative performance are presented. Spectro-radiometric signature models are then discussed in the context of sensor and detection algorithm requirements definition. Specifically, how do we design a hyperspectral sensor with sufficient sensitivity and specificity to meet the application requirements? How do we choose the optimal sensor modality given a concept of operation or deployment? What are the size, weight, power and cost considerations? This design process is then illustrated in a discussion of two prototype systems: a UAS-borne visible/near infrared-shortwave infrared hyperspectral imager for vegetation trait mapping, and a longwave infrared hyperspectral imager employing compressive sensing and a single pixel architecture for chemical plume imaging.Speaker Bio:Dr. Dupuis has over 20 years of experience in the development of novel optical, imaging, spectroscopic, hyperspectroscopic, and radiometric sensors for material detection and analysis. She leads PSI’s Tactical Systems enterprise which encompasses a number of optical detection programs including a compressive sensing hyperspectral imager, a visible-near infrared, shortwave infrared hyperspectral imager, an on-the-move surface contaminant detector based on a spatial heterodyne spectrometer, and a deep-UV Raman spectrometer. Prior to joining PSI, Dr. Dupuis had a 16-year tenure at Optra, Inc., where she served as a Senior Scientist and ultimately the Chief Technology Officer. Dr. Dupuis received a Ph.D. in Electrical Engineering from Boston University. She has an MS in Electrical Engineering from the University of Massachusetts, Lowell, a BE from Dartmouth College, and a BA in Physics from Colby College.Intended Audience:All are welcome. No background knowledge required.
