Editing X-ray machine (section)

==== Operation ====
When baggage is placed on the conveyor, it is moved into the machine by the operator. There is an [[infrared]] transmitter and receiver assembly to detect the baggage when it enters the tunnel. This assembly gives the signal to switch on the generator and signal processing system. The signal processing system processes incoming signals from the detector and reproduce an image based upon the type of material and material density inside the baggage. This image is then sent to the display unit.
