Seeing far is not an attitude but an ability

What is the imaging principle of a thermal imager?


All objects in nature with a temperature above absolute zero -273°C emit electromagnetic waves. Thermal imaging mainly collects infrared light in the thermal infrared band 8μm-14μm to detect the thermal radiation emitted by objects. After detecting thermal radiation, it is converted into grayscale values, and the difference in grayscale values of each object is used to find and identify the target.
