ABSTRACT:
The present invention is a broadband energy illuminator for creating contrast between the broadband energy emanating from a scene and an individual within the scene. A millimeter wave camera is focused toward the individual to detect millimeter wave frequencies reflected from the scene. As an individual passes through scene the millimeter wave camera detects concealed objects by identifying differences in the millimeter wave energy reflected by the individual's body and a concealed object. The broadband energy illuminator focuses a cold source of broadband energy on the scene thereby enhancing the ability of the millimeter wave camera to distinguish the individual's body from concealed objects. A composite image is generated by a central processing unit and displayed on a monitor showing the concealed object on the individual through optical contrast.
