Infrared thermography (IRT), thermal video or thermal imaging, is a process where a thermal camera captures and creates an image of an object by using infrared radiation emitted from the object in a process, which are examples of infrared imaging science. Thermographic cameras usually detect radiation in the long- infrared range of the ...
Infrared (IR) thermography [2] is an analysis technique based on the detection of radiation in the IR part of the electromagnetic spectrum. According to the black body radiation law, all objects with temperature greater than absolute zero emit IR radiation. The device detecting and composing a 2D image of the IR radiation is generally called an ...
Infrared thermography is the science of measuring and mapping surface temperatures. "Infrared thermography, a nondestructive, remote sensing technique, has proved to be an effective, convenient, and economical method of testing concrete. It can detect internal voids, delaminations, and cracks in concrete structures such as bridge decks, highway ...
Infrared thermography specifically refers to a nonintrusive, noncontact mapping of thermograms on the surface of objects using a detector that is sensitive to infrared radiation. [1] There are many other terms widely used, all referring to infrared thermography; the adoption of specific term(s) depends on the author's background and preferences.
Infrared. 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 ...
Thermal radiation in visible light can be seen on this hot metalwork. Its emission in the infrared is invisible to the human eye. Infrared cameras are capable of capturing this infrared emission (see Thermography). Thermal radiation is electromagnetic radiation emitted by the thermal motion of particles in matter. Thermal radiation transmits as ...
Infrared thermometer. An infrared thermometer is a thermometer which infers temperature from a portion of the thermal radiation sometimes called black-body radiation emitted by the object being measured. They are sometimes called laser thermometers as a laser is used to help aim the thermometer, or non-contact thermometers or temperature guns ...
Forward-looking infrared (FLIR) cameras, typically used on military and civilian aircraft, use a thermographic camera that senses infrared radiation. [1] The sensors installed in forward-looking infrared cameras, as well as those of other thermal imaging cameras, use detection of infrared radiation, typically emitted from a heat source (thermal ...
