Abstract
This invention discloses a method for material identification by analyzing the LIBS spectrum of the sample. The LIBS spectrum is pre-processed to equalize the contribution of elements with strong and weak emission lines. In the meantime, the number of spectral variables is reduced to enhance the specificity and minimize the influence of instrument noise. Commonly used spectrum identification and library search algorithms are then applied to the pre-processed LIBS spectrum for material identification.
