TeraSCREEN develops an innovative concept of multi-frequency multi-mode Terahertz (THz) detection with new automatic detection and classification functionalities. The system developed demonstrates, at a live control point, the safe automatic detection and classification of objects concealed under clothing, whilst respecting privacy and increasing current throughput rates. This innovative screening system combines multi-frequency images taken by passive and active imagers which scan the subjects and obtain complementary information, thus allowing for authomatic threat recognition. 



The objective of TeraSCREEN is to develop and demonstrate in a live border control environment a safe, privacy respecting, high throughput security screening system which automatically detects and classifies potential threat objects concealed on a person. This will significantly improve both efficiency and security at border checks. 

The consortium background includes a passive (no emissions) stand-off real-time millimetre-wave imager for security screening. This imager operates at 94GHz. The use of higher operating frequencies, in the Terahertz waveband (above 300GHz, also known as submillimetre-wave), can provide higher image resolution, thus permitting the detection of smaller objects. The combination of several operating frequencies can show up differences between materials in the scene, as the emissive, transmissive, reflective and scattering properties of materials change with frequency. Thus the use of several passive frequencies can increase the detection capability of concealed objects, in addition to providing a first step towards object classification. Outside this project a 220GHz receiver array is being built; TeraSCREEN proposes to develop a 360GHz receiver array to be integrated together with this new 220GHz receiver array and the existing 94GHz imager. This will produce an innovative passive multi-frequency subsystem.

The combination of the passive, multi-frequency subsystem and the active subsystem will produce a completely innovative prototype imaging system. The information provided by this system will be automatically processed and presented to the operator in a way that respects privacy.

The TeraSCREEN Prototype System will have the following features:

  • High throughput – the real-time capability of this system means that the subjects to be screened are not required to stop. This is ideal for border control and security applications as it reduces the time needed for the checks;
  • Non-intrusive – due to the stand-off capability of the system;
  • Safe;
  • Automatic concealed object detection and classification (Automatic Threat Recognition);
  • No privacy issues.
