The Gemini®system’s dual-energy transmission X-rays generate a high-resolution image in which metallic threats, such as guns and knives, are easily detected and fine details, such as tiny wires that could indicate an improvised explosive device, can be discerned. Dual-energy transmission technology uses two X-ray energy levels to determine the “effective” atomic number of objects in the parcel and then colorizes the image based on material type.
The Gemini®system’s Z Backscatter®X-rays generate a photo-like image in which organic materials—such as sheet, bulk, and liquid explosives, narcotics, and plastic weapons—are bright white. The easy-to-interpret images produced by Z Backscatter®technology also help to reduce operator fatigue.
