INFRARED TECHNOLOGY AND CAMERAS

All objects in the world emit thermal energy (heat) the amount of this thermal energy is proportional to the temperature of the object, the hotter the object the more thermal energy (heat) it will radiate. The camera sees these differences and provides an image and identifies the warm and cool areas in different shades or colours. We can see what you can’t.

It is important to understand the theories in how infrared radiation works and how heat transfer affect the objects in a thermal image. Concepts of Emissivity, thermal reflections, thermal conductivity and indirect temperature measurement are critical in identifying and diagnosing problems.

An infrared camera detects infrared energy (heat) and converts it to an electrical signal, which is processed into a thermal image in a camera and video monitor. Heat sensed by the infrared camera can be precisely measured allowing the Thermographer to detect, identify, evaluate and monitor the relative severity of heat-related problems.

Electromagnetic Spectrum

Infrared Thermography is the use of infrared cameras to detect radiation. The primary source of infrared radiation is heat. Infrared cameras detect radiation (heat) in the visible light range of the electromagnetic spectrum in which produce images of radiation.
