Infrared Thermography is the use of an infrared
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. 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 or "heat" radiation 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.
Infra-Red Thermography is a way of making
invisible IR radiation visible. A thermal picture of our
surroundings can be viewed using a thermal imaging
camera so heat energy can be displayed With a
radiometric thermal imaging camera we can detect heat
energy, calibrate the levels of IR, view and store the
information for various applications
-
A photographic camera detects different levels of light
and therefore displays an image that the human eye
recognises
-
A thermal image or thermogram shows different
levels of temperature based on the amount of IR received
by the camera sensor
-
Temperature is around us everywhere so if we use
temperature to define items as healthy, we can also
define items as not healthy or degrading
