Title: Stand-Off Terahertz Imaging and Spectroscopy Detection of Concealed Weapons and Explosives
Agency: DHS
Contract: NBCHC050017
Award Amount: $100,000.00


We propose to develop the design for a stand-off active terahertz imaging and spectroscopy system prototype for the detection of concealed threats at ranges up to 50 meters. Terahertz imaging has the potential to reveal concealed explosives; metallic and non-metallic weapons (such as ceramic, plastic or composite guns and knives); flammables; biological agents; chemical weapons and other threats. Because terahertz imaging employs safe non-ionizing radiation that penetrates clothing, people may be routinely scanned. Images can have sub-millimeter resolution, superior to longer wavelength techniques. Explosives, chemical weapons, and biological agents posses a spectral fingerprint in the terahertz regime. In phase I, elements of a long range time domain imaging system will be demonstrated. Parameters such as range, field of view, resolution, depth of field, size, weight and cost will be estimated.
