'Air laser' may sniff bombs, pollutants from a distance Public release date: 28-Jan-2011 [ Print | E-mail Share ] [ Close Window ] Contact: Steven Schultzsschultz@princeton.edu 609-258-3617Princeton University, Engineering School Princeton University engineers have developed a new laser sensing technology that may allow soldiers to detect hidden bombs from a distance and scientists to better measure airborne environmental pollutants and greenhouse gasses. "We are able to send a laser pulse out and get another pulse back from the air itself," said Richard Miles, a professor of mechanical and aerospace engineering at Princeton, the research group leader and co-author on the paper. "The returning beam interacts with the molecules in the air and carries their finger prints." 'Air laser' may sniff bombs, pollutants from a distance
