  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/Infrared_non-destructive...

    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. Nondestructive testing - Wikipedia

    en.wikipedia.org/wiki/Nondestructive_testing

    NDT is divided into various methods of nondestructive testing, each based on a particular scientific principle. These methods may be further subdivided into various techniques . The various methods and techniques, due to their particular natures, may lend themselves especially well to certain applications and be of little or no value at all in ...
