An object detection portal wherein a video image is obtained of a volume or area being scanned, and location of a threat object is determined and displayed in real time as an indicator overlay on the video image. An individual subject being scanned may be continuously monitored by an operator during an object divesting process, and an operator may view the threat object moving from or remaining with the subject. Object location information is supplied to a video driver to superimpose the overlay on a real time image of a subject. The scanning portal may interact with an exit barrier. The exit barrier may be activated automatically in response to sensing of a threat.

An inspection system including a radio frequency (RF) subsystem and a quadrupole resonance (QR) tube array coil. The RF subsystem may include a variable frequency RF source to provide RF excitation signals at a frequency generally corresponding to predetermined, characteristic QR frequencies of a specimen. The QR tube array coil may be implemented using a plurality of conductive tubes defining a cavity of predetermined volume. Typically, the plurality of conductive tubes are spaced at a distance relative to one another to form at least two non-conductive gaps between tubes in the array. After RF excitation signals are applied to the specimen within the cavity, the QR tube array coil may generate a QR output signal responsive to QR signals generated by the specimen.
