Fusion of Spectral Data from Multiple Handheld Analyzers (LIBS, XRF and Raman) for Chemical Analysis and Classification of Soil

Abstract

An 18-month multidisciplinary project was undertaken by JR Plumer and Associates, LLC and four subcontractors that had three technical objectives: (i) to upgrade current handheld technology for chemical analysis by X-ray fluorescence spectroscopy (XRFS), Raman spectros-copy (RS), and laser-induced breakdown spectroscopy (LIBS); (ii) to design a multisensor system based on these technologies for the rapid, in-situ chemical analysis of soils and other materials of military interest; and (iii) to investigate the classification/discrimination perfor-mance benefit that might be achieved through advanced signal pre-processing and data fusion with XRFS, RS, and LIBS analyses acquired for four suites of natural soils. Accomplishments of the program in the latter area are described in this report.
