This paper shall demonstrate the results of a prototype system to detect explosive objects and obscured contaminated
targets. By combining a high volume sampling nozzle with an inline 2-stage preconcentrator and a Fido, greater standoff
is achieved than with the Fido alone. The direct application of this system is on the Autonomous Mine Detection System
(AMDS) but could be deployed on a large variety of robotic platforms. It is being developed under the auspices of the
U.S. Army RDECOM CERDEC Night Vision and Electronic Sensors Directorate, Countermine Division.
This device is one of several detection tools and technologies to be used on the AMDS. These systems will have
multiple, and at times, overlapping objectives. One objective is trace detection on the surface of an unknown potential
target. By increasing the standoff capabilities of the detector, the fine manipulation of the robot deploying the detector is
less critical. Current detectors used on robotic systems must either be directly in the vapor plume or make direct contact
with the target. By increasing the standoff, detection is more easily and quickly achieved. The end result detector must
overcome cross-contamination, sample throughput, and environmental issues. The paper will provide preliminary results
of the prototype system to include data, and where feasible, video of testing results.
