Washington, June 26: Researchers at the US Department of Energy’s Oak Ridge National Laboratory have demonstrated a device that can detect explosives at distances exceeding 20 yards, by converting reflected light into sound.

ORNL’s technique involves illuminating the target sample with an eye-safe pulsed light source and allowing the scattered light to be detected by a quartz crystal tuning fork.

“We match the pulse frequency of the illuminating light with the mechanical resonant frequency of the quartz crystal tuning fork, generating acoustic waves at the tuning fork’s air-surface interface,” said Charles Van Neste of ORNL’s Biosciences Division.
