Laser device can detect alcohol in moving cars

External laser device detects presence of alcohol vapors inside of a moving car

“This work illustrates how remote sensing technologies affect our everyday life,” said Marco Gianinetto of the Politecnico di Milano, an associate editor with the journal. “We all are already familiar with laser instruments used by the police for speed-limit enforcement. Now these researchers have demonstrated how a laser device could be effectively used for detecting drunken drivers and thereby helping to reduce the number of accidents caused by drivers under the influence of alcohol. In the future, a similar technology may be developed to detect different chemical compounds, enabling the detection of drivers under the influence of other intoxicants.”

The use of the device is simple: The laser system is set up on the side of the road to monitor each car that passes by. If alcohol vapors are detected in the car, a message with a photo of the car including its number plate is sent to a police officer waiting down the road. Then, the police officer stops the car and checks for signs of alcohol using conventional tests.
