From the roadside a laser by cars hunt to see if the driver has drunk. That can so just.

Polish researchers have a laser system built that can check if there in a car alcoholdamp present. By a laser beam through the side window of a passing car to shoot, and this through a series of mirrors on the other side of the road to rebound in detectors, scanning the system, the amount of alcohol vapour inside the interior.

According to the researchers at the Military Technical University of Warsaw in the system with this data, a person’s BAG (blood alcohol percentage) to a tenth of a promille measurement. At least, that was in a test case. They expect that this in persons more precisely.

Nevertheless, we should not depend on it that this is a foolproof system will be. After all, if the director broodnuchter to the BOB, and is, and at the same time, a number of drunken passengers sitting in the car panting, then you have already nothing more to the measurement. Something that the researchers also acknowledge. Even an open window or an air conditioning can give a wrong impression.

Nevertheless, it can be regular alcoholfuiken support. If someone by the laser beam is driving, and there is alcohol detected, then there will be a photo of the license plate forwarded to an agent 100 metres away. Who knows other than, in each case, which cars are alcohol free and are not held-need to be. Saves still sip on a drink.
