Hyperspectral Plarimetric System for Imaging and Detection of Underwater Objects
Abstract
We propose to combine multi/hyperspectral imaging of the ocean with polarization imaging into one system based on a recently developed technology: a non-scanning hyperspectral imager with high frame rates and digitization. The non-scanning feature eliminates the necessity of continual movement, typical for push broom imagers, which limits their capabilities to primarily airborne applications. Integration of three of such nonscanningimagers, each fronted by a polarizer of different orientation, into one package will result in a unique compact polarimetric hyperspectral imaging system which can be used for the remote sensing and object detection in coastal and riverine environments including denied areas from elevated on-shore locations, ships, helicopters and potentially aircrafts, to monitor fast changing features in the ocean at video rates, for the improvement of retrieval of water inherent optical properties (IOPs) and bathymetry. It is intended that these proposed above water observations would be complemented by a full package of in water measurements of IOPs, polarization characteristics and imaging using our existing available in-water instrumentation, as well as by above water measurements from our Long Island Sound Coastal Observatory, part of the AERONET-Ocean Color Network. All projects assume strong involvement of undergraduate and graduate students from Electrical and Environmental Engineering programs.
