    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.
