The facts on both types of airport scanners

(USA)  Imaging Technology  Transportation Security Administration (TSA) 13 Jan 2010
“…….Use of advanced imaging technology is optional to all passengers.

Millimeter Wave

• Millimeter wave technology beams millimeter wave radio frequency (RF) energy in the advanced imaging spectrum over the body’s surface at high speed from two antennas simultaneously as they rotate around the body.
• The energy reflected back from the body or other objects on the body is used to construct a three-dimensional image.
• The three-dimensional image, with facial features blurred for privacy, is displayed on a remote monitor for analysis.

Backscatter

• Backscatter technology uses low level X-ray to create a two-sided image.
• TSA is testing backscatter with an algorithm applied to the entire image to further protect passenger privacy.
