In addition, according to Farran Technologies, a manufacturer of one model of the millimeter wave scanner, the technology exists to extend the search area to as far as 50 meters beyond the scanning area which would allow security workers to scan a large number of people without their awareness that they are being scanned.Īnother body scanning technology, backscatter, comes from American Science and Engineering. Clothing and other organic materials are translucent in some extremely high frequency radio frequency bands. However, if people refuse to go through the scanner, they will then be allowed to go through a metal detector as well as submit to a physical pat down.īeyond the concerns raised by some centering on privacy, it seems that at least as body scanners move into airports, security lines will move more slowly. It also eliminates the need for person to person searches. It can pick up on plastic explosives and ceramic weapons that might otherwise pass through standard security. What makes this millimeter wave airport security scanner unique is that is can detect things that metal detectors cannot. In a separate monitoring area, pictures are evaluated. In Tulsa, people will have to stand facing the scanner and raise their hands. Millimeter waves produce a three dimensional image of persons passing through. It will take a little longer to go through millimeter wave system. The new technology costs about $170,000 a unit compared to $10,000 a unit for metal detectors. Tulsa International Airport just started up body scanning to replace metal detectors.
