Description
The security industry uses a wide range of detector technologies for various applications, primarily cargo and vehicle inspection and baggage and parcel inspection. This discussion focuses specifically on cargo and vehicle inspection. A wide range of detectors are required to be able to detect the vast range of anomalies and threats that can appear in cargo and vehicles. Two primary x-ray detection methods are used: backscatter and transmission imaging. Backscatter detects reflected x-rays and is commonly used to highlight low density materials, which can appear as bright regions in an x-ray image. In contrast, transmission imaging captures x-rays that pass through objects and is commonly used to assess higher density materials, which can appear as darker regions in an x-ray image. Within these two sub-groups of x-ray imaging, different detector technologies and configurations can be used to meet operational needs such as throughput, imaging performance and radiation safety as per customer’s unique needs. In cargo and vehicle inspection, multiple detector technologies can be combined onto one imaging system to support identification of threats, contraband, or anomalies under diverse inspection conditions. The security market is ever-evolving, requiring ongoing research into the development of detector technologies to ensure effective identification of threats and anomalies.
