| 21. | Active thermography uses an external source for measured object excitation, that means introducing an energy into the object.
|
| 22. | But beware : Some printers try to pass off thermography as engraving by calling it engravo-printing or thermograving.
|
| 23. | Firefighters use thermography to see through smoke, to find persons, and to localize the base of a fire.
|
| 24. | Passive thermography has many applications such as surveillance of people on a scene and medical diagnosis ( specifically thermology ).
|
| 25. | Although it lacks the fineness and distinctiveness of engraving, thermography is a less expensive method of achieving raised type.
|
| 26. | Infrared ( IR ) thermography is an analysis technique based on the detection of radiation in the IR wavelength spectrum.
|
| 27. | If an artificial excitation using an external source is applied on the measured object, it is called active thermography.
|
| 28. | It is also fitted in the US Army's MTI system, along with an optical and an thermography imager.
|
| 29. | Maintenance technicians use thermography to locate overheating joints and sections of power lines, which are a sign of impending failure.
|
| 30. | Building envelope thermography involves using an infrared camera to view temperature anomalies on the interior and exterior surfaces of the structure.
