BRICK CLASSIFICATION BY COMBINATION OF PRINCIPAL COMPONENT ANALYSIS AND LINEAR DISCRIMINANT ANALYSIS USING LASER-INDUCED BREAKDOWN SPECTROSCOPY
Original language description
Focusing on historical aspect, during archaeological excavation or restoration works of buildings or different structures built from bricks it is important to determine, preferably in-situ and in real-time, the locality of bricks origin. Combination of principal component analysis (PCA) and linear discriminant analysis (LDA) was applied on LIBS spectra, to classify altogether of 29 brick samples from 7 different localities. Comparison of two potentially field-deployable LIBS setups is introduced. The suggested methodology was tested on LIBS data obtained by stand-off and table-top setup. The table-top arrangement used for experiment was chosen with respect to possible construction of portable device. Lower pulse energy was used (as an alternative for diode-pumped laser) and CCD detector.
