Dielectric Relaxation Analyzing Probe

To address the HSARPA need for a nonimaging handheld multisensory system for bulk detection of threats and illicit objects hidden on a body of a person, under clothing or in body cavities, Physical Optics Corporation proposes to develop a new Dielectric Relaxation Analyzing Probe. This proposed device is based on Electrochemical Impedance Spectroscopy. The DRAP device will offer detection of both conductive and nonconductive objects, and will also work as a metal detector. In Phase I POC demonstrated the feasibility of DRAP through design, fabrication, and evaluation of a conceptual DRAP prototype. In Phase II POC plans to fabricate and demonstrate a prototype of the DRAP handheld multisensory system, verify and validate the probability of detection and false detection rates, and evaluate the potential for threats and illicit objects to be camouflaged. The successful development of this technology at the end of Phase III will benefit the Nation in both government and commercial sectors by providing a versatile and wide detection range handheld screening tool. Commercial applications for this technology include the screening of passengers at checkpoints and cargo at ports of entry into the United States. The device can be used also by security guards, Coast Guards, and police officers.
