A New Airport Scanner Could Make Going Through Security a Breeze

Imagine if going through an airport security was just a matter of walking through a stretch of walls. No pat downs, no x-rays, no metal detectors and no need to remove any clothing at all. Dr. Naomi Alexander invented this body scanner called the "Alfa3" it's based on the technology of millimeter wave imaging. The Alfa3 does not require you to enter a chamber, you just have to raise your arms and stand still while the machine analyzes your body: it is able, instead, to do its job as you simply walk by. Unlike other scanners The Alfa3 uses a passive technology that can detect objects underneath clothing without revealing any anatomical details. “We see the difference in temperature between the body and objects that aren't part of the body” says Dr. Naomi. Right now each Alpha3 scanner is about  a quarter of a million dollars, but is still getting attention from the police, airports etc.and other places like that.
