...Infrared Fever Screening System, inspired by the recent SARS scare, can't diagnose a medical condition. But it can reveal in a moment whether someone is running a temperature--a sign he or she could be sick and warrant a closer look. The system produces a color-coded thermograph of each passerby: red means hot, green means not. Dozens have been sold for use in airports, hospitals, hotels and other public spaces throughout Asia.

...fact, the optics of a typical thermograph somewhat resemble early television. Using tilting and moving mirrors, the Barnes cameras scan the target horizontally and vertically. With each movement of the mirrors, the infra-red detectors take what are, in effect, quick temperature readings of a tiny portion of the subject. Before a picture is completed, as many as 40,000 "bits" of such information may be needed. The picture may be shown simply in black and white with shades of gray representing different temperature ranges. But color can be added with the use of appropriately positioned filters. Whenever there...
Thermography has also proved helpful in finding flaws in aircraft assemblies, checking electronic circuitry and discovering diseased crops. It has even trapped smugglers. Equipped with a thermograph, border police in one Middle Eastern country found unusual heat coming from one area of a water-tank truck. An immediate inspection revealed that part of the cargo was indeed hot; it was a huge haul of hashish...
...letter was given to Arthur D. Trottenberg, manager of operating services, who directed two engineers to investigate the freshman complaint. After installing the thermograph, they checked the instrument daily and found that the temperature in the room went down as low as 59 degrees...
...engineers decided to install a new thermostat, the effectiveness of which they later checked with a new thermograph, which showed the new average temperature of the room to be about 70 degrees. Milano and Amero have since reported that the room has been too hot at times since the new thermostat was installed...
