Fundamentals of the Infrared Physical Layer
Infrared light, commonly referred to as "IR", is a common, easy-to-use, low power and low-cost media to transmit information. Among the few "wireless" communication choices, IR has the significant advantage of compatibility with hundreds of millions of electronic devices with IR ports (i.e., laptop...

Infrared Thermometers Tutorial
The Royal Astronomer Sir William Herschel discovered "Dark Heat" radiation in 1800. In 1880 the term "infrared" was coined. Samuel Langley invented the bolometer that measures variations of resistance when heated. In 1901 a bolometer could detect a cow at 400 meters. After World War II, many...

Applications for High-Speed Infrared Imaging
objects in the infrared region of the spectrum, either to detect them or to measure their surface temperature. Conventional infrared cameras have time constants similar to the human eye, so they, too, are often at a loss when it comes to photographing fast-moving hot targets. Other types of targets...
