    en.wikipedia.org/wiki/Infrared_and_thermal_testing

    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 ...

    en.wikipedia.org/wiki/Infrared_non-destructive...

    Active thermography is an advanced nondestructive testing procedure, which uses a thermography measurement of a tested material thermal response after its external excitation. This principle can be used also for non-contact infrared non-destructive testing (IRNDT) of materials. The IRNDT [1] method is based on an excitation of a tested material ...

  4. Thermographic inspection - Wikipedia

    en.wikipedia.org/wiki/Thermographic_inspection

    Thermographic inspection refers to the nondestructive testing (NDT) of parts, materials or systems through the imaging of the temperature fields, gradients and/or patterns ("thermograms") at the object's surface. It is distinguished from medical thermography by the subjects being examined: thermographic inspection generally examines inanimate ...

    en.wikipedia.org/wiki/Thermography

    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 ...

    en.wikipedia.org/wiki/Nondestructive_testing

    Nondestructive testing (NDT) is any of a wide group of analysis techniques used in science and technology industry to evaluate the properties of a material, component or system without causing damage. [1] The terms nondestructive examination (NDE), nondestructive inspection (NDI), and nondestructive evaluation (NDE) are also commonly used to ...

  7. Fourier-transform infrared spectroscopy - Wikipedia

    en.wikipedia.org/wiki/Fourier-transform_infrared...

    The term may also refer to Frustrated total internal reflection. Fourier-transform infrared spectroscopy (FTIR) [ 1 ] is a technique used to obtain an infrared spectrum of absorption or emission of a solid, liquid, or gas. An FTIR spectrometer simultaneously collects high-resolution spectral data over a wide spectral range.
