Infrared is an energy similar to visible light, but with a longer wavelength. Infrared energy is invisible to the human eye, however, while visible light energy is emitted by objects only at a very high temperature, infrared energy is emitted by all objects at ordinary temperatures....

[Every body emits infrared radiation. Blackbodies absorb and emit 100% of the radiation related to their temperature. All other bodies are placed in relation to this when evaluating their radiation emission, called emissivity.
Infrared radiation (IR), sometimes referred to simply as infrared, is a region of the electromagnetic radiation spectrum wherewavelengthsrange from about 700 nanometers (nm) to 1 millimeter (mm). Infrared waves are longer than visible light waves but shorter than radio waves. Correspondingly, the ...
Objects coming in the range of these invisible illuminators absorb or reflect these infrared waves. The infrared radiation emitted by or reflected from warm objects is detected and picked up by long-wave thermal infrared imagers. The thermal imager lens directs the infrared rays onto an infrared...
While infrared sensors detect heat (which then triggers an alert) the actual temperature has a wide range. This is because every sensor is built differently. Typically, we’ve found that the average infrared sensor will detect heat in a range of -40 to 1000 degrees Celsius. ...
How does Infrared Work? What are Night Vision Goggles? What is an Infrared Thermometer? Discussion Comments Bydonna61— On Mar 17, 2011 This is great information, thanks. I love this technology. I work in the medical field and we are always trying to get the word out about how this is...

Similar to the visible light spectrum, which ranges from violet (the shortest visible-light wavelength) to red (longest wavelength), infrared radiation has its own range of wavelengths. The shorter "near-infrared" waves, which are closer to visible light on the electromagnetic spectrum, don't em...
Infraredis a new generation technology that is used to transfer data from one infrared enabled device to another by lining up the infrared 'eye' with other devices. TheInfrared Data Association (IrDA)defines physical specifications communication protocol standard for the short-range exchange of data ...
