From smoother airport security lines to deterring smugglers, baggage x rays are the silent guardians of our travels. From the conveyor belts of airplanes and trains to the doors of government buildings and parcel sorting centers, these machines are used all over the world to scan luggage, revealing prohibited items for security personnel to inspect and address without risking human lives or causing unnecessary delays.
An X-ray machine uses high-energy radiation to send beams of light across a bag’s contents. Dense objects such as metals absorb more X-rays, while less dense objects such as clothing or water bottles scatter them. The scanner’s computer then creates a visual representation of the scanned item in an image that is displayed on the operator console for security personnel to interpret.
Using specialized software, the operator can see the differences between different items. For example, organic substances like drugs and explosives appear as shades of orange in the images because they have specific densities that distinguish them from other materials. This information can then be interpreted by security personnel to determine the appropriate course of action for each situation.
The type of scanner you choose will depend on the size and complexity of your typical baggage items, as well as your security requirements. For instance, you’ll want to select a single- or dual-view scanner depending on whether speed or precision matters more. Single-view machines are generally faster than dual-view units because they don’t require the extra step of rescanning items from two different angles. On the other hand, dual-view scanners offer more precise results and are typically used in high-security scenarios where precision is valued over rapid processing times.
