Abstract

The Hyperspectral Polarimetric Imaging (HPI) Testbed system combines a dual-band hyperspectral imager (VNIR and SWIR), a 3-axis polarimetric imager, and a high resolution panchromatic imager. All imagers operate through a common fore-optic, and thus have identical fields of view, with simultaneous image capture. The HPI testbed system was developed to aid a sentry in the surveillance of broad sectors for intrusion by ground vehicles or other non-natural objects. The various image components are readily combined through image fusion, which lends itself well to anomaly detection algorithms. This paper describes the general HPI testbed system design and performance, and also provides a detailed description of the polarimetric imaging system, calibration methods, and performance.
