What is the principle of x ray baggage scanner?

The principle of an X-ray baggage scanner is based on the ability of X-rays to penetrate through different materials and produce images of the contents of an object. The X-ray source produces X-rays that pass through the luggage and are captured by an array of detectors on the other side. The detectors convert the X-rays into an electrical signal, which is processed by software to create an image of the contents of the baggage. The image is displayed on a monitor, allowing security personnel to quickly and easily inspect the contents of the luggage for any potential security threats. The X-rays used in baggage scanners are carefully controlled to ensure that the exposure to passengers and operators is within safe limits
