Abstract

A method and apparatus utilizing a series of optical components and systems which effectively detect and locate electromagnetic imaging or detection systems or devices, such as cameras and passive infrared detectors. A light source is arranged in a specially-prescribed manner, and is used in conjunction with imaging optics to illuminate an area. Any electromagnetic imaging or detection system in the illuminated area is detected with either the user's eye directly, or with detection optics to determine the existence of such electromagnetic imaging or detection system.
