Baggage scanners utilize X-ray technology to create images of the contents of luggage, allowing security personnel to identify potential threats like weapons or explosives. The process involves X-rays passing through the luggage, with different materials absorbing the rays at varying degrees, creating a visual representation of the items inside. The scanner converts the data from the detectors into an image, where different materials appear with varying shades or colors based on their density. Security personnel analyze the image to identify any potential threats or prohibited items based on their appearance. The scanner emits a beam of X-rays that passes through the luggage.
