| titleOfInvention | Method and apparatus for detecting and locating camera illuminators |
| abstract | A method and apparatus is described whereby invisible camera illuminators may be readily identified and located. In one embodiment the method of detecting the presence of an imaging system producing an invisible illuminator includes introducing a first optical filter capable of blocking energy from an LED infrared illuminator band source and allow energy from broadband visible light source to pass with minimal attenuation; and introducing a second optical filter that permits most of the energy from said infrared illuminator to pass and blocks a substantial portion of said broadband visible light; wherein said filtered LED infrared illuminator and said broadband visible light blink on and off. |
