A fiber-optic probe designed for remote laser-induced breakdown spectroscopy (LIBS), Raman spectroscopy, and Raman imaging has been developed for the microanalysis of solid samples. The probe incorporates both single-strand optical fibers and an image guide and allows atomic emission and Raman analysis of any spot on a solid sample within a 5 mm diameter field of view. The real-time sample imaging aspects of the probe are demonstrated by measuring LIBS spectra from different regions of a granite sample and by measuring the Raman spectra of individual TiO2 and Sr(NO3)2 particles on a soil substrate. The ability to obtain remote Raman images of the TiO2 and Sr(NO3)2 particles on the soil substrate is also demonstrated. In this paper we discuss the design and implementation of the fiber-optic probe for obtaining LIBS spectra, Raman spectra, and Raman images.

Concentration Depth Profiles

At Naval Base Point Loma in San Diego, California, a canyon had been filled with construction debris and automotive scrap residue (ASR), the latter of which included lead acid batteries. A magnetic survey and induced potential (IP)/DC resistivity survey showed the presence of anomalies at the western end of the site where historic records indicated that the ASR had been placed. Lead concentration depth profiles were obtained in situ and in real time at the site using a direct push fiber-optic laser-induced breakdown spectroscopy (FO-LIBS) sensor probe. Lead, along with strontium and titanium, was detected at depths of 7 to 8 m bgs. These results provided confirmation that the magnetic/IP anomalies at the site are due to ASR.
