More on Passive Millimeter Wave Technology

Some folks are getting the wrong idea that the SPO-7 passive millimeter wave technology used at Denver and Minneapolis-St. Paul airports during the recent conventions is a mobile Millimeter Wave portal and can see through clothing. That’s not the case. These are two separate technologies that look for threats in different ways.

The Millimeter Wave portal - the booth you walk into at checkpoints in certain airports - penetrates garments and provides an image. The SPO-7, which uses passive millimeter wave technology to detect threats from a distance, produces an image, but it’s simply the type of image you would see on a video camera. Images are not stored.

The SPO-7 unit consists of two separate sensors and a monitoring location. By simultaneously comparing the illumination levels from two locations on an individual’s body, the SPO-7 detects potential threats such as suicide vests and other improvised explosive devices (IEDs) that are hidden under individuals’ clothing. On the screen, it produces a light, using a red-to-green scale, that suggests anomalies such as the presence of explosives. That's why the screen and the officer viewing the screen doesn't need to be in a remote location.

Security officers operating the SPO-7 will work closely with Behavior Detection Officers. The teams will be equipped with wireless headsets to communicate with each other about possible concerns. TSA also partners closely with local law enforcement who will respond if called.

Unlike the stationary (and large) millimeter wave portal, the SPO-7 is mobile and only requires a few hours of training for use. This comes in handy to provide an additional layer of security in specific areas, in both the aviation, mass transit and maritime environments.

In crowded public areas such as ferry terminals, mass transit stations and most recently, airports, the SPO-7 works without breaking passengers’ stride.

And lastly, to address safety and privacy concerns, the SPO-7 does not shoot X-rays or any other type of radiation at people. It merely measures energy that emanates from the human body. Signage is prominently displayed where the SPO-7 is used to notify the public. SPO-7 enables TSA to add an unpredictable security measure without adding inconvenience to passengers.

The SPO-7 pilots will continue at the Denver and Minneapolis-St. Paul airports for 60-90 days.

So, the two key things you should take away from this post are:

The SPO-7 cannot see through your clothing.

The SPO-7 does not project X-rays or any other types of radiation.

Here are some screen shots of what the operator sees:

New Security Technologies Make Airport Debut

Blogging has been light this week, with some on the team out for end-of-summer vacations and Bob's out taking care of his new baby.

So this week, as one political convention comes to a close and another is about to start, we wanted to highlight a story on our website about two new technologies that have been deployed in the two convention city airports. Those traveling through Denver and Minneapolis-St. Paul might see these explosives and threat detection technologies that have previously been used in other modes of transportation and can be flexibly deployed to airports.

The technologies are passive millimeter wave, a mobile technology which has been used in maritime and mass transit to detect the characteristics of explosives hidden on the body. It is completely safe, non-invasive and does not store information. A hand-held spectrometer can penetrate sealed containers in seconds and identify a wide range of solid and liquid explosives using laser technology.

To learn about other ways TSA and other Department of Homeland Security components are working to keep convention travel and sites safe, check this out.

We'll get back into the regular swing of things next week, and we hope all of our readers enjoy a safe and fun Labor Day weekend.
