SUMMARY

A critical technology effort explored the viability of applying advanced non-destructive testing methods in detection of explosives.  The assessment was followed by screening technologies which are impractical or do not meet the requirements.  Out of the screened technologies, optimal alternative strategies were defined to develop a concept for the RSDC.  The selected technology was the use of prompt gamma nuclear detector and x-ray backscattering.  Consideration of using gas chromatography as a second tier was shown to have promise. The formulated concept was analyzed and evaluated.  Plans for demonstration were also made.

Patent #1 Abstract

The invention is a detector for detection of concealed explosives, drugs and contraband using x-rays imaging and powder pattern techniques and ultrasonics. In case of inspection of carry-on baggage a combination of computer-aided x-ray transmission imaging and x-ray diffraction analysis is used to screen, confirm and localize threats. The x-ray transmission is used to segregate dense baggage and cargo which are inspected by x-ray backscatter imaging to identify suspicious objects. All suspicious objects are carefully analyzed by x-ray diffraction. In another embodiment a slow processing system uses diffraction for identification of threats and x-ray radiography for localization of the objects. In case of drugs concealed in compartments aboard marine vessels or air crafts a hand-held x-ray system is disclosed which can be used in three modes of operation: x-ray transmission, x-ray backscatter, or x-ray diffraction dependent on the architecture of the compartment. In case of buried mines an oscillating dual-energy x-ray backscatter imaging is used for antipersonnel mines and a combination of x-ray backscatter imaging and prompt gamma detectors is used for antivehicle and antiaircraft mines. Ultrasonic detectors are disclosed for detection of explosives on persons. Also, a tracking system based on bar-code identification system and a central computer is disclosed for baggage.
