Development of a Hybrid UV Scanner System

Screening, detection, and identification of explosives and illicit drugs at aviation checkpoints, border crossings, and U.S. ports of entry represent an especially challenging requirement for DHS and TSA. To address this, DHS and its components have deployed multi-layered risk-based detection equipment (e.g. IMS, Raman & FTIR sensors, etc.) to address these challenges. Additionally, DHS Screening at Speed (SaS) program is requiring new techNlogy which can locate trace residues and particles more accurately and faster. To support this goal, Alakai proposes development of a Hybrid UV Scanner that combines UV two different UV spectroscopic techniques. The first technique provides rapid 100% scanning of the luggage with good detection sensitivity and scan speed but possibly a higher than desired false alarm rate. A follow on UV Raman system would automatically (with N human involvement) sample the potential threat target for final confirmation.
