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 electromagnetic spectrum (roughly 9,000–14,000 nanometers or 9–14 μm) and produce images of that radiation, called thermograms. Since infrared radiation is emitted by all objects with a temperature above absolute zero according to the black body radiation law, thermography makes it possible to see one's environment with or without visible illumination. The amount of radiation emitted by an object increases with temperature; therefore, thermography allows one to see variations in temperature. When viewed through a thermal imaging camera, warm objects stand out well against cooler backgrounds; humans and other warm-blooded animals become easily visible against the environment, day or night. As a result, thermography is particularly useful to the military and other users of surveillance cameras.

Fields in which these techniques are used:

• Commercial and Residential, roof and insulation check

• Industrial, asset maintenance (above ground storage tank, vessel inspections)

• Program process monitoring

  • Quality control in production environments

  • Predictive maintenance (early failure warning) on mechanical and electrical equipment

• Agriculture, e.g., Seed-counting machine

• Building inspection

• Fault diagnosis and troubleshooting

  • Energy auditing of building insulation and detection of refrigerant leaks

  • Roof inspection

  • Home performance

  • Moisture detection in walls and roofs (and thus in turn often part of mold remediation)

  • Masonry wall structural analysis

• Thermography (medical) - Medical testing for diagnosis

  • Veterinary thermal imaging
