Uses of Thermal Imaging
Infrared
Thermography is the use of an infrared thermal imaging
and measurement camera to "see" and "measure" thermal
energy emitted from an object.
Thermal, or Infrared Energy, is light that is not visible because its wavelength is too long to be detected by the human eye; it's the part of the electromagnetic spectrum that we perceive as heat. Unlike visible light, in the infrared world, everything with a temperature above absolute zero emits heat. Even very cold objects, like ice cubes, emit infrared radiation. The higher the object's temperature, the greater the infrared radiation emitted. Infrared allows us to see what our eyes cannot.
Infrared Thermography cameras produce images of invisible infrared radiation or "heat" and provide precise non-contact temperature measurement capabilities. Nearly everything gets hot before it fails, making infrared cameras extremely cost-effective, valuable diagnostic tools in many diverse applications. And as industry strives to improve manufacturing efficiencies, manage energy, improve product quality, and enhance worker safety, new applications for infrared cameras continually emerge.
A Thermal Image or thermogram shows different levels of temperature based on the amount of Infrared radiation received by the camera sensor which can then be used to analyse the object and give an idea of its condition.
Infrared Thermography is being used in every day applications to assess, for instance, how much heat is being lost from a building, How the brakes on a car perform and how quickly skin heals around a wound after an operation. Applications for temperature measurement can be found everywhere:
An Infrared Camera provides a method of seeing this heat in a simple, easy to interpret two dimensional form.
