A false-color image of two people taken in long-wavelength infrared (body-temperature thermal) radiation. This pseudocolor infrared space telescope image has blue, green, and red corresponding to wavelengths of 3.4, 4.6, and 12 μm, respectively. Infrared ( IR; sometimes called infrared light) is electromagnetic radiation (EMR) with ...
Feb 27, 2019 · According to Robert Mayanovic, professor of physics at Missouri State University, infrared spectroscopy, such as Fourier transform infrared (FTIR) spectroscopy, is highly useful for numerous ...
3 days ago · infrared radiation, that portion of the electromagnetic spectrum that extends from the long wavelength, or red, end of the visible-light range to the microwave range. Invisible to the eye, it can be detected as a sensation of warmth on the skin.

Image infrarouge moyen d'un petit chien en fausse couleur obtenue en utilisant une caméra thermique. Le rayonnement infrarouge (IR) est un rayonnement électromagnétique de longueur d'onde supérieure à celle du spectre visible mais plus courte que celle des micro-ondes ou du domaine térahertz.
Infrared (IR) and Thermal Technologies. Two types of infrared security cameras are available, each with very different technologies. Laser IR illuminators and thermal imaging are both part of the infrared spectrum, which is measured by the amount of energy in a lightwave related to its wavelength.
Infrared radiation (IR), sometimes referred to simply as infrared, is a region of the electromagnetic radiation spectrum where wavelengths range from about 700 nanometers (nm) to 1 millimeter (mm). Infrared waves are longer than visible light waves but shorter than radio waves.
