用于激光诱导击穿光谱的深光谱CNN

Deep Spectral CNN for Laser Induced Breakdown Spectroscopy

Juan Castorena, Diane Oyen, Ann Ollila, Carey Legget, Nina Lanza

摘要:

这项工作提出了一种光谱卷积神经网络(CNN),对激光诱导击穿光谱(LIBS)信号进行操作,以学习(1)将光谱信号与传感器不确定性的来源(即,预处理)和(2)得到给定光谱信号的样品的化学含量的定性和定量测量(即,校准)。一旦光谱CNN经过训练,它就可以通过单个前馈通道完成任何一项任务,具有实时优势,并且没有任何额外的辅助信息要求,包括暗电流、系统响应、温度和探测器到目标的范围。我们的实验表明,所提出的方法优于现有的方法所使用的火星科学实验室的预处理和校准的遥感观测火星漫游车,“好奇”。

英文摘要:

This work proposes a spectral convolutional neural network (CNN) operating on laser induced breakdown spectroscopy (LIBS) signals to learn to (1) disentangle spectral signals from the sources of sensor uncertainty (i.e., pre-process) and (2) get qualitative and quantitative measures of chemical content of a sample given a spectral signal (i.e., calibrate). Once the spectral CNN is trained, it can accomplish either task through a single feed-forward pass, with real-time benefits and without any additional side information requirements including dark current, system response, temperature and detector-to-target range. Our experiments demonstrate that the proposed method outperforms the existing approaches used by the Mars Science Lab for pre-processing and calibration for remote sensing observations from the Mars rover, 'Curiosity'.
