摘要:
激光诱导击穿光谱技术是激光技术的重大发明，因其能够对物质元素进行无损、高灵敏度、快速的定性与定量分析，成为污染物检测、食品安全检测、元素痕量分析等领域重要的技术手段。经过多年发展，激光诱导击穿光谱技术以其具有的独有技术优势，在多个领域表现出了巨大的潜在应用价值，并且国外同行已将这项技术应用到核电站安全监控、空间探索、工业检测等领域。相对于国外的研究进展，国内开展此项技术的研究起步较晚，尤其在应用领域存在较大差距。本文综述激光诱导击穿光谱技术的发展历程，概述该技术的基本原理，突出应用领域及其特点，并分析对检测结果的影响因素。
Laser-induced breakdown spectroscopy is an important invention. It has the characteristics of no damage, high sensitivity and rapid qualitative and quantitative analysis of material elements, so it has been widespread concern of pollutant monitoring, food safety inspection and trace element analysis etc. After years of development, the technology of laser-induced breakdown spectroscopy (LIBS) is given many technical advantages in the field of multiple with potential appliance value. The LIBS has been widely used abroad, such as nuclear power plant safety monitoring, space exploration and industrial inspection etc. However, study on LIBS in China started late; especially in the field of application, there is a big gap. It described the development of laser-induced breakdown spectroscopy, basic principles, application field and characteristics, and analysed the impact factors of testing result.
