Abstract:
1. A thermal imaging system comprising an infrared imaging system including a camera, a micro processor and a display unit, said infrared imaging system being positioned at a checkpoint, said infrared imaging system measuring temperature by sensing thermal radiation naturally emitted by people passing the checkpoint, the camera having a lens, an optical system and a photodetector, the lens being only focused on discrete points of a narrow area positioned above the eye and below an eyebrow at a brain tunnel temperature of a face of the individual passing by the checkpoint, the photodetector quantifying energy flux in a mid infrared range naturally emitted from the brain temperature tunnel by the people passing by the checkpoint as viewed by the optical system of the camera, the display unit displaying a thermal image of the brain temperature tunnel area of the face of the individual as viewed by the lens of the camera as the individual passes by the checkpoint, the infrared imaging system measuring a specific temperature span of the brain temperature tunnel of a person passing the checkpoint of between two to five ° C. in relation to a reference compared to the narrow area located at the brain temperature tunnel.
