4.2 Holographic Detections

The holographic imaging system was designed to identify hidden weapons, explosives, and other contraband, such as plastic, ceramic, and other non-metallic weapons.

The Department of Energy's Pacific Northwest National Laboratory, Richland, Washington, developed for the Federal Aviation Administration a system to scan airline passengers when passing through airport security checkpoints. (proquest.umi.com, 2003). System u ses millimetre waves to generate holographic images. The holographic imaging system is distinctly different from current surveillance systems that rely on metal detectors, X-ray imaging, and, in some cases, baggage and body searches. Metal detectors cannot screen for plastic or ceramic weapons, plastic explosives, or other types of non-metallic contraband, while X-ray imaging subjects people to potentially harmful ionizing radiation.

The imaging system has enormous potential for use in screening people at points of entry to mass transit systems, including airports, subways, and trains; border crossings; government installations such as courtrooms, military bases, prisons, embassies, and office buildings; crowded public places such as sports arenas, concert halls, museums; and commercial buildings.
