摘要

Acousto-Optical Tunable Filter (AOTF) Based Spectral Imaging technology, also known as hyperspectral imaging, has demonstrated
particular promise for rapidly scanning surfaces, capturing and identifying different spectral signatures present in an optical field to
measure levels of biological contamination. Since each surface has unique spectral profiles, changes in the spectral profile can be
identified and analysis of the changes in the spectral profile can enable determination of residual contamination on a range of such
surfaces. Moreover, the intrinsic polarimetric capabilities of AOTFs can be useful in applications such as IED detection since it can be
used to identify regions of disturbed surface material, e.g., road surface, dirt, etc., thereby bringing to attention areas of potential
buried IEDs. It also offers the unique potential to detect unburied IEDs by their spectral or polarimetric signature. We will present
research into solutions and initial results based on recently patented hyperspectral polarimetric imaging technology in these domains.
The development and evaluation of this technology is expected to result in the demonstration of a “first-of-type” new sensor capability
with remarkable operational characteristics. This sensor, which can be flown on an unmanned aerial vehicle (UAV/UAS) platforms.
