Project Description

Overview and Significance

A national security goal is the uniform screening of all cargo and checked baggage. Meeting this goal is challenging because of the volume of goods to be screened and the nature of screening required. This project aims to develop accurate physics-based models of cargo and checked baggage sensing, and to use these models to create methods for physics-based reconstruction and explosives recognition using novel multispectral modalities for cargo imaging. These methods will incorporate tools from compressed sensing and computational imaging to yield superior image quality from reduced measurement geometries and limited photon budgets that are typical for cargo applications. The methods developed will lead to more accurate and efficient screening of cargo, improving throughput, increasing detection, and reducing false alarm.

This system uses the conventional method of localization based on the combined use of source and sensor collimation, and thus collects only a small fraction of the fluorescence emissions.
