How Does The Thermal Imager Work
- Jul 03, 2017 -

Popularly speaking thermal imager is the object of the invisible infrared energy into a visible thermal image. The different colors above the thermal image represent the different temperatures of the measured object.


By looking at the thermal image, it is possible to observe the overall temperature distribution of the target to be measured, and to study the heat of the target, so that the next step can be judged. The modern thermal imager works by using optoelectronic devices to detect and measure radiation and establish interconnections between radiation and surface temperature. 

All objects above absolute zero (-273 ° C) emit infrared radiation. The thermal imager uses the infrared detector and the optical imaging objective lens to accept the infrared radiation energy distribution pattern of the target to be reflected on the photosensitive element of the infrared detector to obtain the infrared thermal image, the thermal image of the thermal image and the surface of the object Corresponding.
