Working Principle

 

The core of uncooled thermal imaging works on the principle of microbolometer. Its core component is the microbolometer, which is usually composed of a layer of thermosensitive material that is sensitive to infrared radiation, such as vanadium oxide (VOx) or amorphous silicon (a-Si).
When infrared radiation is irradiated on the microbolometer, the thermosensitive material absorbs infrared energy and changes its temperature. Since the resistance value of the thermosensitive material changes with temperature, this resistance change will cause the current or voltage passing through the microbolometer to change accordingly. Then, these electrical signals are collected by the detector, and after a series of processing such as amplification and analog-to-digital conversion, the analog signal is converted into a digital signal.
Finally, the digital signal is transmitted to the image processing unit, and after algorithm processing, different colors or grayscales are assigned according to different temperature values, thereby generating an intuitive thermal imaging image, allowing people to clearly see the temperature distribution on the surface of the object.
