How does a baggage scanner work?

When the baggage is kept on the conveyor belt, the x-rays hit two detectors. The first detector collects energy and position of the x-rays which are low-energy and as they continue towards the second detector, the rays are blocked by a filter that only allows high energy. Thus, the second detector can collect only high energy. These two outputs from the detectors are compared with the help of data converters and converted into a high-resolution image of the objects on the photo detector.
The imaging analysis is used to assign colors of the objects on the photo-detector based on the atomic numbers. 3 color or 6 color-coding is done for the baggage passing through the lead-lined curtains. Organic materials like paper, food, and cloth are in orange, light metals are in green and dense metals are in blue. The denser the material, the darker is the color.
