<title>Three-dimensional imaging polarimetry</title>

Abstract

A multi-dimensional laser radar sensor is developed to perform 3D imaging polarimetry. The imaging polarimeter is an extension of the existing, well-developed Streak Tube Imaging Lidar technology. With polarization optics added to the transceiver system, simultaneous capture of 3D high- resolution polarimetric and reflectance imagery is achieved over wide fields of view. Laboratory and field experiments exhibit the capability of the imaging polarimeter for enhancing clutter reduction, image segmentation, and target discrimination for low contrast and camouflaged targets.
