Aerial standoff detection with the High Efficiency Multimode Imager (HEMI)

摘要

The High Efficiency Multimode Imager, HEMI, is a combined Compton and coded mask camera designed to detect and image gamma rays from ∼30 keV up to a few MeV. It consists of individual 1-cm3-size CZT detector modules with an energy resolution of ∼2%. Their modularity allows for a wide range of detector setups and application scenarios. Here we present modeling results for an aerial standoff detection system based on HEMI detectors.
