Our research focuses on the following:

(1) Hyperspectral Imaging. This area includes both imaging spectrometer instrumentation for remote sensing and signal processing algorithms for material detection, tracking, identification, and characterization. Novel imaging spectrometer designs that achieve excellent spectral resolution, field-of-view, and radiometric sensitivity in the visible through longwave infrared spectral region are being pursued. We are particularly interested in miniature devices for employment from small airborne platforms and designs that support simultaneous spectral imaging in a staring format. Signal processing advances are investigated for low contrast target detection in diverse clutter backgrounds, change detection over large environmental variations, and featured-aided target tracking.

(2) Polarimetric Imaging. This area includes investigations of techniques for on-chip multispectral and polarimetric filtering at visible through longwave infrared wavelengths, including methods using nanostructured filters and quantum detector structures. Material phenomenology and signal processing methods associated with enhanced object discrimination and shape estimation from polarimetric imagery are also being explored.

(3) Multimodal Infrared Sensing. This area focuses on the design and implementation of new hardware and signal processing methods for simultaneously capturing spectral, temporal, spatial (two- and three-dimensional), polarimetric, and radiometric information of remotely sensed objects using emitted and reflected passive infrared radiation. A specific application of interest is feature-aided tracking of vehicles and personnel in urban areas.
