Paper Abstract

The Mini-Raman Lidar System (MRLS) is a 'proof-of-principle' chemical sensor that 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. The device has potential application to 'first responders' at the site of a chemical spill. The MRLS is portable and has been used both in the lab and in the field. Theoretical estimates and actual laboratory data suggest the possibility of detecting contaminants with a surface coverage of less than 1g/m2 at a distance of three meters for one second of signal integration. Increasing the optical throughput efficiency, integrating pattern recognition software, and incorporating a laser with a wavelength near 250 nm are the primary goals for the development of a prototype system.
