Laser equipment is expected to detect drunk driving in the future

    Drunk drivers trying to dodge a breathalyser test should beware, as researchers have developed a laser device that can remotely detect whether a driver is drunk or not. The laser beam is fired from a mobile car by a team at Warsaw's Military University of Technology, samples alcohol vapor, passes through a reflector and is then picked up by a detector.

    With the help of a breathing device that can simulate drunk driving, the researchers easily detected blood alcohol concentrations exceeding 0.1% (in the United States, if the blood alcohol viscosity exceeds 0.08% or higher, it can be considered illegal drunk driving). Of course, if a real drunk person is used for the experiment, this laser device can also work with very low alcohol concentrations.

    However, the device is not perfect at present. If the drunk driver opens the windows or turns on the air conditioner in the car, the system that detects the concentration of alcohol vapor will obviously be "abused" badly. In these cases, the system will sound an alarm to remind the traffic police that these cars should stop for inspection. Of course, researchers from the Warsaw University of Technology expressed the hope that this system can be more integrated and that other parameters can be monitored to obtain more accurate results. If the law allows the normal use of this device in the future, many drunkards who "got away with it" before may be in trouble. It can not only reduce the workload of traffic police, but also avoid some serious accidents caused by escaping punishment.
