no journal, ,

The two dimensional distribution measurement is possible using the laser induced breakdown spectroscopy. We analysed the two-dimensional composition distribution measured by LIBS using the least-squares method. As the result, distribution of the contribution ratios of a sample provided using the least-squares method expressed element distribution of the samples well.
