The SafetySpect scanner uses ultraviolet light to detect an enzyme in human saliva, making the saliva show up as white spots under the scanner’s glow. In this Sept. 1 photo, Fartash Vasefi (left), SafetySpect’s chief technology officer, and UND Associate Professor Joe Vacek test the system in the cockpit of a UND aircraft.
