In general, people who drink alcohol often think they are OK. However, the facts justify the fact that most people will become impotent after drinking alcohol. Therefore, drunk driving often leads to a variety of unnecessary tragedies. At present, China and even the whole world attach great importance to this issue. In addition to various legal provisions, supervision is also a very important point. Nowadays, the method used by the traffic police to check drunk driving is generally through the form of blowing air. This must have been made clear by everyone.
This newly developed laser-based alcohol measurement method uses an interband cascade laser technology and is similar to the non-contact explosives detection method used in airports and large-scale events. People set up a special laser device on the roadside to illuminate passing vehicles. The light is reflected by a mirror located across the road. At this time, the laser can detect the presence of alcohol molecules inside the vehicle based on the spectral distribution of the reflected light, and these alcohol molecules are likely to be exhaled by drunk drivers.
This will help the police quickly find those "suspicious" vehicles and carry out more systematic investigations. It is also possible to avoid unnecessary tragedies caused by it.
