Thermal imaging principle

Principle: The thermal imager uses an infrared detector and an optical imaging objective to receive the infrared radiation energy distribution pattern of the measured object and reflect it on the photosensitive element of the infrared detector, thus obtaining an infrared thermal image corresponding to the thermal distribution field on the surface of the object.

Generally speaking. A thermal imager converts invisible infrared energy emitted by an object into a thermal image visible to the naked eye. Different colors on the thermal image represent different temperatures of the measured object.

Extended data:

By looking at the thermal image, we can observe the overall temperature distribution of the measured target, study the heat of the target and judge the next work. ?

The working principle of modern thermal imager is to use photoelectric equipment to detect and measure radiation and establish the correlation between radiation and surface temperature. Moreover, objects above absolute zero (-273℃) will emit infrared radiation.
