视频演示：毫米波全身成像系统工作原理

Beams of radio frequency (RF) energy in the millimeter wave spectrum are projected over the body’s surface at high speed from two antennas simultaneously as they rotate around the body

The RF energy reflected back from the body or other objects on the body is used to construct a three-dimensional image

The three-dimensional image of the body, with facial features blurred for privacy, is displayed on a remote monitor for analysis

What to Expect

Each passenger will walk into the millimeter wave portal. Once inside, they will be asked to stand in two different positions and remain still for just a few moments while the technology creates a three-dimensional image of the passenger in real time

Once complete, the passenger will exit the opposite side of the millimeter wave portal

Images will be deleted immediately once viewed and will never be stored, transmitted or printed (the passenger imaging units have zero storage capability)

What TSA Sees

Millimeter wave technology produces images which are viewed by a Transportation Security Officer in a remote location

Detection

Metallic or non-metallic devices and objects are displayed, including weapons, explosives and other items that a passenger is carrying on his/her person

Safety

For comparison, the energy projected by the system is 10,000 times less than a cell phone transmission

We, and all objects around us, generate millimeter wave energy - and we are exposed to it every single day of our lives
