The main function of thermal imaging night vision devices at night is to use the difference in heat emitted by the object itself to form an image, so that targets and obstacles can be clearly identified in a completely dark environment.
Generally divided into two types: passive and active:
Passive thermal imaging night vision device: This type of night vision device does not emit infrared rays, but relies on the infrared radiation of the target itself to form a "thermal image". It forms an image by detecting the difference in heat emitted by the object, so it is also called a thermal imager. Passive thermal imaging night vision devices can also work effectively in a completely dark environment because it does not require an external light source.
Active thermal imaging night vision device: This type of night vision device uses an infrared searchlight to illuminate the target and then receives the reflected infrared radiation to form an image. Although active night vision devices require an external light source, they can still provide clear images in harsh environments such as rain and fog because they are not affected by external light.
Application scenarios and advantages of thermal imaging night vision devices: Thermal imaging night vision devices are widely used at night, especially in complex environments:
1. Adaptability to complex environments: Whether it is dark, rainy, foggy or mountainous roads, thermal imaging night vision devices can accurately identify heat source targets such as people, cars and animals.
2. Early warning: With the ability of early warning, drivers can make judgments before potential dangers occur and avoid accidents.
3. Multi-mode switching: Supports three visual mode switching of visible light, infrared imaging and dual-light fusion to adapt to different light environments.
