Millimeter Scanning at Airports: Is It Worth the Cost?
TulsaInternationalAirport just started up body scanning to replace metal detectors. The new technology costs about $170,000 a unit compared to $10,000 a unit for metal detectors. It will take a little longer to go through millimeter wave system.
Millimeter waves produce a three dimensional image of persons passing through. In Tulsa, people will have to stand facing the scanner and raise their hands. Faces are blurred. In a separate monitoring area, pictures are evaluated.
