Germany has developed the latest laser alcohol measurement method. Spectral detection cures drunk driving. There is laser pointer often a big hidden danger in current driving safety, which is the problem of drinking and driving. Because generally speaking, people who drink alcohol tend to think that they are good.
But the facts just proved that most people will become ill after drinking. Therefore, drinking and driving often leads to all kinds of unnecessary tragedies. At present, our country and the whole world attach great importance to this issue. In addition to various legal provisions, supervision is also a very important point.
At present, the method of traffic police to check for drunk driving is generally through the form of blowing air. This must be clear to everyone. Now, Germany has developed a more advanced and precise method to make drunk driving nowhere to hide! This technology was developed by the University of Würzburg in Germany. It is a method of detection using green laser pointer. When the blood alcohol concentration of a person in the car reaches 1/10000, the device can detect and alarm.
According to reports, this measurement system uses inter-band cascade laser technology, similar to the principle of non-contact explosive detection methods used in airports and large-scale events. People set up a special laser device on the side of the road to illuminate passing vehicles. The light will be reflected by the mirror located on the opposite side of the road.
At this time, the laser can detect whether there are alcohol molecules inside the vehicle based on the spectral distribution of the reflected light, and these alcohol molecules are likely to be exhaled by the drunk driver. In this way, it can help the police quickly find those “suspicious” vehicles and conduct a more systematic investigation. It is also possible to avoid unnecessary tragedies caused by this.
