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 ...
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 ...
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]
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.

Frost & Sullivan analysis in the global NDT equipment market in 2012 estimated the magnetic and electromagnetic NDT equipment market at $220 million, which includes conventional eddy current, magnetic particle inspection, eddy current array, and remote-field testing. This market is projected to grow at 7.5% compounded annual growth rate to ...
Condition monitoring techniques are normally used on rotating equipment, auxiliary systems and other machinery like belt-driven equipment, (compressors, pumps, electric motors, internal combustion engines, presses), while periodic inspection using non-destructive testing (NDT) techniques and fit for service (FFS) [1] evaluation are used for ...
