Terrorists were targeting commercial airliners long before the 9/11 attacks on the World Trade Center and the Pentagon. Despite heightened security measures, commercial airliners remain an attractive target for terrorists, as evidenced by the August 2006 terrorist plot to destroy as many as ten aircraft in mid-flight from the United Kingdom to the United States. As a response to the security threat air carriers are now required to screen 100-percent of all checked baggage for explosives. The scale of this task is enormous and the Transportation Security Administration has deployed thousands of detection systems. Although this has resulted in improved security, the performance of the installed systems is not ideal. Further improvements are needed and can only be made with new technologies that ensure a flexible Concept of Operations and provide superior detection along with low false alarm rates and excellent dependability. To address security needs Applied Signal Technology, Inc. is developing an innovative and practical solution to meet the performance demands of aviation security. The neu-VISIONTM system is expected to provide explosives detection performance for checked baggage that both complements and surpasses currently deployed performance. The neu-VISIONTM system leverages a 5 year R&D program developing the Associated Particle Imaging (API) technique; a neutron based non-intrusive material identification and imaging technique. The superior performance afforded by this neutron interrogation technique delivers false alarm rates much lower than deployed technologies and "sees through" dense, heavy materials. Small quantities of explosive material are identified even in the cluttered environments.
