Analysis of the imaging principle of thermal imaging night vision equipment
The thermal imaging night vision system can produce realistic and clear thermal images in conditions of total darkness, mist, and smoke. It can seamlessly connect with widescreen navigation systems and multifunctional navigation systems.
The camera lens can freely rotate 360 degrees horizontally and pitch up and down ± 90 degrees, allowing you to experience the sensory enjoyment and safety guarantee brought by military technology. Designed to enhance the driver's visual ability.
The system can output clear thermal images of the road conditions ahead in harsh weather conditions such as full darkness, haze, and low visibility such as glare from headlights, effectively improving the driver's visual range.
At the same time, only pedestrian recognition and front vehicle collision warning functions can detect pedestrians, vehicles, and obstacles in advance, greatly improving driving safety.
Principle of thermal imaging night vision instrument:
Thermal imaging is passive infrared, which is generated by receiving the temperature (thermal energy) of an object and processing it into an image for display. Generally, the image is grayish white regardless of day or night.
Thermal imaging is not active infrared, and the thermal imaging night vision device itself does not emit infrared rays, but only receives individual infrared rays;
So it's easy to come to the conclusion that as long as thermal imaging can receive the infrared emitted by the object, there will be image output. Conversely, if infrared is not received, it cannot reflect the image of the object we want to see.
So now we are all asking some questions, such as:
The ability of thermal imaging to perspective, penetrate walls, view people and objects inside cars, and penetrate glass has certain results.
If you pass through walls or glass, the wall blocks the infrared rays, and the thermal imaging night vision system cannot receive infrared rays and cannot detect objects on the other side of the wall and glass.
That is to say, if there is an image, it must not be completely blocked by all sealed objects, otherwise infrared imaging will definitely not be received.
In environments such as trees and grass, thermal imaging can still detect objects that are hotter than plants due to not completely blocking infrared light.
If there are people and animals behind the grass and trees, it is obvious that there is a temperature difference. Objects with high temperatures will light up, while objects with low temperatures will be darker.
Thermal imaging is actually temperature difference imaging. Objects with high temperatures emit stronger infrared radiation, while objects with low temperatures emit relatively weaker infrared radiation.
