Optical Emission Spectroscopy is used within the LIBS (Laser-Induced Breakdown Spectroscopy) technique to measure the elemental composition of a sample irradiated by a laser pulse. When the objective is to characterize a known alloy or to analyze the sample semi-quantitatively, standards can be used. This method refers to the “calibrated LIBS”. When the studied sample is complex (for instance unknown alloy and/or concentration gradients), the modeling of the experimental emission spectra leads to the determination of the laser-induced plasma characteristics including its composition. This second method refers to the “calibration-free LIBS”.

直读光谱法用于 LIBS（激光诱导击穿光谱法）技术中，用于测量激光脉冲照射的样品的元素组成。当目标是表征已知合金或半定量分析样品时，可以使用标准品。此方法是指“校准的 LIBS”。当研究的样品很复杂（例如未知合金和/或浓度梯度）时，实验发射光谱的建模可以确定激光诱导等离子体特性，包括其组成。第二种方法是指“免校准 LIBS”。
