Three Prototypes for Standoff Trace Chemical Detection

Three different prototypes of a standoff trace chemical detection system were developed under the IARPA SILMARILS Program in order to advance the technological readiness of this class of sensor. Two of the prototypes utilize a cryo-cooled mercury-cadmium telluride (MCT) camera to achieve high performance capability. The third prototype utilizes a low-cost microbolometer camera and is targeted for applications that require small size and low cost. Applications include vehicle and person borne suicide bombers, airport screening, package screening and customs screening. In this talk, we will discuss the design and performance of all three prototypes.
