SWOrRD: Swept Wavelength Resonance-Raman Detection of Bacteria, Chemical and Explosives

Abstract

Detection of bacteria, chemicals or explosives with Raman scattering is fast, noncontact, does not require chemical supplies and is adaptable to robotic vehicles; making Raman ideal for many military and civilian applications. In this technique, a laser is used to illuminate an area which may contain the sought after substance. Some of the laser light is absorbed by the molecular vibrational and rotational states of the substance, and is re-emitted (scattered) at wavelengths slightly different than the wavelength of the illuminating laser.
