According to R. James Seffrin‚ a director for the Definitive Internet Resource for Infrared Thermography‚ Seffrin explains that all objects emit infrared radiation as long as the object is above absolute zero (Kelvins). The cameras that can see and distinguish temperature are called‚ “thermal imagers.” These imagers convert the perceived radiation into scaled colors

Passive infrared sensor A passive infrared sensor (PIR Sensor) is an electronic sensor that measures infrared light radiating from objects in its field of view. They are most often used in PIR-based motion detectors. Operating principle All objects with a temperature above absolute zero emit heat energy in the form of radiation. Usually this radiation is invisible to the human eye because it radiates at infrared wavelengths‚ but it can be detected by electronic devices designed for such a purpose

Experiment 6 Infra-Red Spectroscopy of HCl and DCl gas Abstract Fourier-transform infrared spectroscopy has been very useful in helping scientists examining molecules of HCl and DCl. Because deuterium has a greater mass than hydrogen‚ the IR band shown for HCl is at a higher wavelength than DCl. The absorption of light in DCl was at lower frequency 1700-2200 cm-1 because D is bigger and heavier. That’s why the vibrations on the IR were shorter for DCl compared to HCl. The stretching of

next generation video format. Sony’s Blu-Ray technology was backed by a consortium that included Philips‚ Matsushita‚ Hitachi‚ and others. Toshiba’s HD-DVD had the backing of the DVD Forum‚ making it the “official” successor to the DVD format. Both companies lined up major movie studios and video game consoles to promote their standards (Sony’s Playstation 3 and Microsoft’s Xbox 360). In January 2008‚ Time Warner’s announcement that it would support Blu-Ray instead of HD DVD triggered a chain reaction
