Abstract. The results
of experiments concerning detection of alcohol vapors in car cabins using a
laboratory device, which was developed and built at the Institute of
Optoelectronics at the Military University of Technology, are described. The
work is a continuation of the investigations presented in an earlier paper. On
the basis of those results, the whole device was designed and built. Then it
was investigated using a car with special system simulating a driver under the
influence of alcohol. To simulate the appropriate concentration of alcohol in
human blood, a special method of generation of alcohol vapor was developed.
