The recognition capability of the identification system using Raman spectroscopy is increasing with the demands in the field. Among the various approaches that determine the identity of a target, signal correlation using a moving window is one of the most effective and intuitive methods. In this paper, we report a new correlation method that is robust to spectral intensity variations. Using the peak distribution of a given spectrum, this method adaptively determines meaningful spectral regions for the identification target. Three commercial Raman spectrometer and a 14 033 library were included in the study, which was used for a library-based chemical discrimination test and mixed material analysis experiments. According to the identification experimental results, the proposed method correctly identified all of the spectra and maintained a mean correlation score above 0.95 while maintaining the correlation score of nontarget materials as low as possible.

拉曼光谱识别的自适应命中质量指数。

使用拉曼光谱的识别系统的识别能力随着领域的需求而增加。在确定目标身份的各种方法中，使用移动窗口进行信号相关是最有效，最直观的方法之一。在本文中，我们报告了一种对光谱强度变化具有鲁棒性的新的相关方法。使用给定光谱的峰值分布，此方法可自适应地确定识别目标的有意义的光谱区域。该研究中包括三台商用拉曼光谱仪和一个14 033库，该库用于基于库的化学鉴别测试和混合材料分析实验。根据鉴定实验结果，
