Abstract

In this work, a new spectral reduction algorithm for the echelle spectrometer was proposed. Unlike conventional approaches, the key concept in this algorithm is to model the spectrogram rather the spectrometer, which makes the algorithm more adaptive to different designs. This algorithm also introduces a dynamic adjusting procedure for generating optimized spectra from laser-induced plasmas. This additional step improved the spectrum stability and absolute line intensity of the spectrum and yielded better quantification performance. Experimental results demonstrated that the quantification results of analyzing aluminum alloy samples were improved using this new algorithm.
