The difference between thermal imager and night vision

The biggest difference between night vision and thermal imagers is that their working principles are different: thermal imagers convert invisible infrared energy emitted by objects into visible thermal images, and night vision devices actively receive through an image enhancement system. The light source, the night vision device must have an external light source illuminated on the object and reflected to the night vision device before it can be imaged. The principle of thermal imager:In layman's terms, a thermal imager converts the invisible infrared energy emitted by an object into a visible thermal image. The different colors on the top of the thermal image represent the different temperatures of the object being measured. By viewing the thermal image, you can observe the overall temperature distribution of the measured target and study the heating of the target. All objects above absolute zero
