Security Platform
Static Security CT (EDS / LEDS)
Conventional Explosive Detection Systems rely on mechanically rotating X-ray tubes that limit inspection speed and long-term stability. STRETTA’s Static Security CT replaces mechanical rotation with electronically sequenced multibeam emission, enabling inspection architectures defined by control electronics rather than moving mass.
Security Environment
Detection Systems Under Growing Throughput Pressure
Global aviation and cargo security face increasing operational demands. Passenger volumes continue to grow, threat profiles evolve, and regulatory standards for explosive detection and material discrimination become more stringent.
Airport operators simultaneously require higher throughput, lower false alarm rates and reduced lifecycle costs.
Most CT-based Explosive Detection Systems rely on mechanically rotating gantry architectures. A single thermionic X-ray tube is accelerated around the inspection volume to generate projection geometry.
Rotational inertia constrains acquisition speed. Bearings and slip rings introduce wear. Higher inspection throughput amplifies mechanical stress and increases long-term maintenance requirements.
Security CT should scale with electronics, not with rotating machinery.
System Architecture
From Mechanical Motion to Electronic Beam Sequencing
STRETTA’s Static Security CT platform removes these limitations at the architectural level. The system is built on STRETTA’s proprietary multi-beam platform technology and replaces mechanical tube rotation with electronically sequenced X-ray emission.
Spatially distributed focal spots are activated in deterministic microsecond sequences while the gantry remains mechanically stationary.
Only electrons move.
Projection geometry is defined electronically rather than mechanically produced. This eliminates rotational inertia, removes slip rings and bearing wear, and decouples acquisition speed from mechanical acceleration curves.
Emission Control
Stable Geometry and Spectral Output by Design
Reliable threat detection depends on stable photon energy and consistent projection geometry. Detection algorithms for dual-energy and multi-energy material discrimination require precise spectral control across all projections.
The static architecture is enabled by the STRETTA Integrated System (SIS).
STRETTA’s proprietary emitter arrays are orchestrated by an FPGA-based Electronic Control System (ECS), while a dynamically stabilized High Voltage Generator (HVG) maintains spectral consistency during rapid pulsed switching.
Real-time voltage regulation compensates dynamic switching events and preserves photon energy stability across projections. Deterministic emission control ensures the spectral stability required for automated threat detection.
Integration with Security OEM Platforms
Industrial Validation
Static Security CT is not a theoretical concept. STRETTA’s linear multibeam X-ray tube prototypes have been delivered to and quality-accepted by a leading global security OEM for airport baggage CT applications.
This validation demonstrates industrial manufacturability, integration readiness within certified security inspection platforms.
Static Security CT represents a transition from mechanically optimized scanners toward electronically orchestrated inspection platforms designed for scalable throughput and future regulatory evolution.
