Abstract

An explosives detection system which includes computed tomography (CT) (30) and quadrupole resonance (QR) (35) sensors for identifying particular explosive compounds present in passenger baggage. The CT sensor may be configured to automatically identify the presence or absence of bulk military, commercial, and sheet explosives during CT scanning of the baggage. Similarly, the QR sensor may be configured to responsively generate RDX and PETN signals during QR scanning of the passenger baggage. Using any of a variety of inspection protocols, the explosives detection system may generate an output alarm (25) based upon data obtained from CT and QR sensors.
