Infrared Thermography is equipment or method or a process which senses infrared energy emitted from equipment, converts into temperature and gives the thermal image of the equipment. “Infrared” refers invisible radiant energy. “Thermography” refers method of analyzing heat or thermo coming out of a body.
Infrared thermography services are provided by using Infrared thermal imaging cameras. The thermal imaging camera has a special lens which detects infrared light (heat) emitted by all objects. This focused light is scanned by a phased array of infrared detector elements. Temperature distribution image data of infrared thermography consists of matrix of pixels (number of detector: for example, 320 horizontal X 240 vertical pixels). Thermal image data can be transferred to PC. Subsequently, the data can be calculated and utilized freely. Thermal image data is colored up pixel by pixel based on temperature.
- It is invisible since its wavelength is longer than visible light
- Naturally emite from any object’s temperature is absolute zero(0K) or higher
- It has a characteristic of heating an object. Therefore, it is sometimes called “heat wave”.
- It is a kind of light (electromagnetic wave) It can be transmitted through vacuum
