FAQ

Those interested in the Backscatter millimeter wave scanner category often ask the following questions:

☑️ How does a backscatter millimeter wave scanner work?

  • How Millimeter Wave Scanners Work. Backscatter machines use a device called a collimator to produce a parallel stream of low-energy X-rays, which pass through a slit and strike a passenger standing in the machine. A single scanner includes two radiation sources so that both the front and the back of the person can be imaged.

☑️ How precise is a millimeter wave scanner?

  • Millimeter wave scanners produce a special type of microwaves with wavelengths that fall in a range exactly between 0.001 meters (1 millimeter) and 0.01 meters (10 millimeters). In other words, the waves emitted by mmw scanners are much larger and therefore have less impact on small structures, such as human proteins and nucleic acids.

☑️ How does the millimeter wave scanner software work?

  • A millimeter wave scanner with ATR software produces a generic outline of a person -- exactly the same for everyone -- highlighting any areas that may require additional screening. A problem occurred.

☑️ How does a millimeter wave body scanner work?

  • A millimeter-wave body scanner uses two antennas that rotate around a person’s body to construct a 3-D image that resembles a fuzzy photo negative. The image is sent to a remote monitor. Millimeter-wave technology does not use x-rays and does not add to a person’s ionizing radiation dose.

☑️ How does a millimeter wave scanner work at an airport?

  • Millimeter wave scanners have been in use in many airports since May 2013. The scanner processes an image by using colors to mark out any areas that may require further screening. However, when a green “GO” sign like the traffic light appears on the screen without an outline or box, it means the passenger is cleared to proceed.
