ABSTRACT: A system that operates at room temperature and that could scan for concealed weapons from standoff distances of >10 m would be a tremendous asset for US military homeland security personnel worldwide. THz imaging can, potentially, be used for this application, but it requires the development of a new class of THz detectors whereby the signal to noise ratios are improved significantly. Tanner Research is proposing the use of multiplicative mixing THz detectors for this purpose. In Phase I, we demonstrated an initial class of prototype devices that are consistent with such multiplicative mixers, and we documented the potential benefits of such devices as ca. 40 to 70 dBs. In Phase II, we will demonstrate such multiplicative mixing THz detectors, and also demonstrate the metrics associated with it’s use. At the end of the Phase II project, we will have mitigated all risk elements associated with the science, and will be in a position to initiate a commercialization effort. BENEFIT: A standoff THz imaging system capable of detecting concealed weapons and explosives from a standoff distance of >10 m would significantly enhance the capabilities of US personnel around the world. Specifically, in Afghanistan, the IED remains the insurgents’ weapon of choice, and the proposed system would significantly reduce the potency of IEDs.
