With the development of economy and society, the rapid increase in the number of cars not only increases the traffic pressure, but also buries many traffic hidden dangers. At present, car accidents have become a public hazard and one of the four major causes of death in cities. Driving at night is the most dangerous for drivers, because the visibility of drivers at night is poor, and the illumination range and brightness of car lights are limited. The infrared thermal imager images by detecting the infrared rays emitted by objects, and the strong light does not affect its imaging. Even in the case of total darkness, smoke, rain and snow, it can clearly image and accurately judge the road conditions ahead, so it is very suitable as the front end of night vision system.

Now it has been widely used in the transportation tools of the army, such as vehicle pilot, armored vehicle periscope pilot, armored vehicle sight, submarine periscope, aircraft forward-looking infrared system and so on.
