TSA screeners at Phoenix Sky
Harbor Airport will begin testing a new type of screening machine
CBS News reports the machine, built by L-3 Communications, uses
"millimeter-wave" imaging technology to scan passengers for weapons
The devices works in similar fashion to the controversial "backscatter" technology,
which PHX rolled out in February of this year. Both systems give
screeners explicit images of passengers' bodies, although certain
anatomical areas are blurred in the interest of propriety.
Millimeter-wave technology allows a thorough scan to be
performed in less time than by using backscatter, according to CBS.
If tests at PHX are successful, similar machines will be deployed
at JFK International, and Los Angeles International.
As with the backscatter devices, the use of millimeter-wave
screening will be voluntary, and only used for passengers selected
for secondary screening. Those passengers may opt to be scanned by
the machine, rather than be patted down.
