  2. Thermographic inspection - Wikipedia

    en.wikipedia.org/wiki/Thermographic_inspection

    When compared with other classical NDT techniques such as ultrasonic or radiographic testing, thermographic inspection is safe, nonintrusive, and usually noncontact, allowing the detection of relatively shallow subsurface defects (a few millimeters in depth) under large surfaces (typically covering an area of 30 by 30 cm (12 by 12 in) at once, although inspection of larger surfaces is possible ...

  3. Active thermography - Wikipedia

    en.wikipedia.org/wiki/Active_thermography

    Active thermography is an advanced nondestructive testing procedure, which uses a thermographic measurement of a tested material thermal response after its external excitation. This principle can be used also for non-contact [1] infrared non-destructive testing (IRNDT) of materials. [2]

  4. Infrared and thermal testing - Wikipedia

    en.wikipedia.org/wiki/Infrared_and_thermal_testing

    Infrared and thermal testing refer to passive thermographic inspection techniques, a class of nondestructive testing designated by the American Society for Nondestructive Testing (ASNT). [1] Infrared thermography is the science of measuring and mapping surface temperatures. "Infrared thermography, a nondestructive, remote sensing technique, has ...

    These activities are leveraging the different techniques of NDT like ultrasound, radiography, tomography, penetrant, infrared thermography, magnetization, shearography or Eddy current that allow the detection and assessment of a defect on metallic or composite materials (CFRP, ALM, HRD). Example of testing

  7. Non-contact thermography - Wikipedia

    en.wikipedia.org/wiki/Non-contact_thermography

    Non-medically licensed alternative practitioners who are not held to the same standard may offer thermography services but that should not be confused with the field of medical thermology. Restated, medical thermology is the use of infrared (IR) imaging to assess skin temperature as an extension of the clinician's physical exam to aid in the ...
