PM: TECH UPDATE: Frisking From Afar: OCT 95 Popular Mechanics magazine




Millimeter-wave camera picks up both metallic and plastic concealed 
handguns.

DEERFIELD, MA-Between microwave and infrared lies the millimeter wave
band. This little-heralded portion of the electromagnetic spectrum
turns out to be perfect for "remote frisking." Millitech Corp. has
designed a camera to accomplish just that.

The idea calls for measuring the time delay and intensity of
millimeter wave energy that radiates naturally. At millimeter
wavelengths, people are good emitters, while metals are very poor.
Dielectric objects, such as plastics, ceramics and powdered drugs,
are somewhere in between. Clothing and building materials, such as
wallboard,  are virtually transparent.
