AOTF Polarimetric Hyperspectral Imaging for Mine Detection.

Abstract

This paper reports an analysis of polarimetric hyperspectral imagery of an outdoor scene containing a number of inactive mines. The imagery was taken with a visible/near-infrared acousto-optic tunable filter prototype system. The result has illustrated that the characteristics of mine smooth surfaces can create high signals in polarization difference images and consequently provide a quick and reliable approach for detection.
