Short-range, Non-contact Detection of Surface Contamination Using Raman Lidar

摘要

The application of a novel mini-Raman Lidar to the standoff detection and identification of chemical spills is discussed. The new chemical sensor combines the spectral fingerprinting of solar-blind UV Raman spectroscopy with the principles of lidar to open a new venue of short-range (meters to tens of meters), non-contact detection and identification of unknown substances on surfaces. In addition to discussing experimental results collected with a "proof-of-principle" system, a next generation system, currently under development, is also presented
