(Jan. 25, 2010) The dielectric portal technology uses microwave energy to interrogate a passenger to detect the presence of metallic or nonmetallic objects. This scanner measures dielectric constant of a human body surface by means of the determination of the reflection coefficient of microwave radiation. Continue reading →

(Jan. 22, 2010) Passive millimeter wave technology is based on the principle that any object not in absolute zero temperature will emit electromagnetic energy at all wavelengths. Continue reading →

(Jan. 22, 2010) Active millimeter-wave imaging combines a source of millimeter wave energy with a detector and works as radar does, “illuminating” the area to be searched with millimeter waves and then imaging the reflected waves. This technology uses low energy, low intensity reflected x-rays to scan an object to generate an image. Continue reading →

(Jan. 20, 2010) Whole body imagining backscatter technology was created to enhance security in airports and other vulnerable areas, and can detect liquids, contraband, ceramics, explosives, narcotics, concealed currency and weapons. Whole Body Imaging Backscatter technology relies on a narrow, low intensity x-ray beam scanned over the body’s surface at high speed. Continue reading →
