- Lasers detecting explosives from 20 meters away
- Oak Ridge National Laboratory ORNL researchers have developed a super-sensitive explosives detector which uses a laser and a device that converts reflected light into sound. Interestingly, the technique they've used is based on earlier works of Alexander Graham Bell in the late 1880s. In their experiments, the researchers used three...
