Forwardscatter Detector System

Non-intrusive inspection imaging systems are used by military and law enforcement security operations to view the interiors of vehicles and cargo at checkpoints and facility entry control/access points. American Science & Engineering, Inc. developed the Forwardscatter Detector (FSD) System to complement its existing Z-Backscatter X-ray Systems, including the Z-Backscatter X-ray Van (ZBV). While the Z-Backscatter technology is designed to detect bulk organic objects, the FSD System provides an additional capability for detecting bulk metallic objects by positioning FSDs opposite the x-ray source to capture forward-scattered x-rays. The FSD System is suitable for use with fielded ZBVs; can be mounted on a fi xed barrier or on a military trailer; and is operable in portal mode by having the vehicle/cargo move between the FSD and the ZBackscatter X-ray source. In addition, system operators are able to simultaneously view the Z-Backscatter and Forwardscatter images, thus enhancing their ability to examine vehicles and cargo for concealed weapons, contraband, and other threat items.
