远程LIBS结合拉曼光谱探测系统检测物质成分分布
A laser induced breakdown spectroscopy and Raman spectroscopy combined remote detection system for material composition analysis
摘要
Abstract
We develop a laser induced breakdown spectroscopy (LIBS) and Raman spectroscopy (RS) combined detection system for remote detection of substance composition.It can scan a 2-dimensional region with scanning accuracy of 2 mm and detect element contents and elementary surface distribution in samples at the maximum distance of 30 m away from the detector.Using our 2-dimensional scanning system,we analyze Fe element distribution on the surface of wollastonite at a distance of 30 m.According to the time difference between LIBS signal and Raman signal,both LIBS and Raman spectrum signals are collected by a gated intensified CCD (ICCD) camera.The experimental result shows that the system can be applied to identify the type of aluminum alloys and also be used in alloy sorting process to save resources and energy.The system can also be applied in remote mineral identification.Molecular information such as C-O,S-O and Si-O stretching patterns can be obtained from Raman spectroscopy analysis of minerals and rocks,thus distinguishing minerals and rocks,i.e.carbonates,sulphates and silicates.关键词
