In some specific places, such as highway intersections and urban fringes, for security reasons, it is necessary to monitor the interior of the car.However, with the advancement of technology, the anti-peeping function of car windows has become more and more powerful, and it is difficult to see the actual situation inside the vehicle through naked eyes or ordinary monitoring.It is difficult to confirm whether the personnel inside the vehicle are safe, whether the items carried are dangerous goods, etc.
There is a camera on the market called a laser through window camera.The use of band laser lighting can effectively shield stray light, only receive light that is in the same direction as the lighting source, and finally image clearly.The advantage of this camera is that it has the advantages of long monitoring distance and automatic adjustment of lens focal length.
Laser is another major invention of mankind besides nuclear energy, semiconductors, and computers in the 20th century. The laser through-window camera can realize long-term day and night monitoring, and can return images to the monitor in real time.It is widely used for public security, special police anti-terrorism, border anti-smuggling, and urban security construction.
Now there is a nanosecond gated imaging technology on the market, which does not require supplementary lighting, filtering and other technologies. By manipulating the time, the interference light can be suppressed up to 108, which solves the problem of glass curtain walls, smoke, and fire. The instrument, called the Penetration Imager.
The working principle of the penetrating imager is to use: nanosecond pulsed laser illumination and nanosecond shutter synchronization to slice space at different distances, and the camera only collects target signals in the slice; thus greatly suppressing ambient light (light, sunlight, fire) and Medium (smoke, fog, rain, snow) scattering interference to achieve high-contrast imaging.
The penetrating imager combines the advantages of window-through imaging and inverse strong light imaging of the laser through-window imager, and can also realize the functions of fire-through imaging and smoke-through imaging;
The scope of application has expanded to urban fire rescue, forest fire rescue and other scenarios, providing more effective protection for the safety of the people and rescuers.
