What is security? • The automatic and unobtrusive screening of goods in transit for the detection of illicit materials and illegal trade. • The automatic and unobtrusive screening of people in transit for the detection of illicit materials and weapons and for rapid confirmation of their identity • The automatic and unobtrusive screening of documents, both electronic and paper based, for authenticity and accuracy

Sources in use today • X-Ray tubes • Transmission X-Ray and CT (140 – 450kVp) • Accelerators • High energy X-ray (2 – 9MV) and neutron • Radioactive • Co-60, Cs-137, Cf-252, … • Non-Ionising • kHz to THz, passive and active
Sensors in use today – Ionising Radiation • X-ray (Integrating) • Scintillator + PD (CsI, Gadox, CdWO4) • Gamma-ray (Spectroscopic & Integrating) • Scintillator + PMT (NaI) • Neutrons • Scintillator + PMT (Various options) • Gas detector (BF3, He3)
Sensors in use today – Non-Ionising • RF • kHz (localised detection) • MHz (not much activity) • GHz (imaging) • THz (imaging) • Optical • IR (Thermal), Visible (CCTV), Raman, … • Mass Spectroscopy • Explosives/Narcotics detection
Algorithms in use today • X-ray image based • Materials discrimination (dual-energy) • Explosives detection (regulated) • Spectroscopic • Spatially resolved materials analysis (kHz to visible) • Sample based chemical analysis (Raman, Mass Spec) • Time of flight • Explosives detection (neutrons)
Interfaces • Human interfaces • Graphical, item analysis • Graphical, system level • Machine interfaces • Databases (system and system of systems) • Intelligence (national, regional, global)
Current challenges • Automation • Algorithms needed for high detection, low false alarm rate inspection with minimal human intervention • Standoff detection for people • Detection of suspects in crowded places such as transport interchanges and stadia at large distances (100m) • High throughput cargo screening • Driven by US requirement for 100% container screening
Current challenges (continued) • Clutter • Complex images and scenes to analyse • Interference in spectroscopic systems • Environmental specifications • Ambient temperature ranges and ramp rates, ambient humidity, mechanical shock
What is an industry ready prototype? • Source or Sensor that provides new or improved functionality, ruggedised to point of use outside laboratory • Algorithm with demonstration of required performance on real data • Interface that handles realistic data rates and data volumes
