A multi-dimensional laser radar sensor is developed to perform three-dimensional imaging polarimetry. The imaging polarimeter is an extension of the existing, well-developed Streak Tube Imaging Lidar (STIL) 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.

An imaging lidar system is developed for capturing laser-induced fluorescence imagery. With minor changes to the transmitter and receiver optics, the system operates in a number of different modes including 3D multispectral, hyperspectral, multi-excitation hyperspectral, and fluorescence-lifetime hyperspectral. All of these sensor functions provide discriminating capabilities for targets exhibiting spectral fluorescence signatures.
