New for November 2011!
This page was put up by request of a microwave engineering student
from Iran. We don't have much content on microwave imaging, but
perhaps we can attract some!
Microwave imaging is a very broad
Imaging for security
Microwave imaging is a growing
field, it is used in airports throughout the world in concert with
other security measures such as metal detection and baggage X-ray.
There are principally two type
of imagers, passive and active. Passive uses "natural"
radiation from people to take a peek, while active illuminates the
subject with RF energy and examines the backscatter.
Imagers in airports can be handheld,
There is controversy surrounding
the ability of imagers to see beneath clothing. However, the quality
of the image makes it a poor substitute for pornography, and your
image is not really identifiable, so quit your whining and do what
the nice officer says. It takes a few seconds to gather and process
the RF energy, be sure to hold still!
Back on June 25, 2003, TSA security
lab director Susan Hallowell allowed her body to be scanned by an
early version of the backscatter system. This one image set the
industry back five years! Now full body scanners are deployed at
many airports, it has become part of routine screening.
