Body Scanner

Full-body scanners are very effective in detecting objects concealed under a person’s clothing, without having the target remove hisher clothing or without physical contact. The procedure is faster – over in 15 seconds – than frisking, and avoids the intrusive aspect of frisking that some people find degrading.
Millimeter wave scanner technology is based on the principle that clothing is translucent in some EHF (Extremely High Frequency: 30 – 300 GHz) RF bands.
Passive Millimeter Wave technology uses scanners that read the raw energy that is naturally emitted by the human body and by objects carried on the human body. The scanner generates a facsimile of the target based on the interpretation of these energies.The main advantage of Passive Millimeter Wave Scanner technology is that it is very safe for both the screener and the target, since there is no artificially generated energy directed at the target. As a consequence of the fact that the scanner relies on natural energy radiation, the resolution of the image generated by the scanner is not very high, which is a drawback; which in turn means that anatomical details of the target are indistinguishable, which is a plus with privacy advocates.
