探索和利用新的科学技术方法和技术手段,解决文化遗产研究中的文物化学组成、文物年代、遗址勘探等一些重要问题已十分急迫。20世纪70年代末出现的混频激光光谱分析技术,具有高光谱分辨率、低检出限、可无损分析等优点,为解决这些难题提供了新的方法。对混频激光光谱分析技术的原理、特点和目前应用现状进行了介绍,并分析了该项技术在我国文化遗产研究中的应用及其前景。 To explore and make use of new scientific and technological methods and technical means to solve some important issues in the cultural relics chemical composition, cultural relics, and site exploration has become extremely urgent. In the late 1970s, mixed-spectrum laser spectroscopy, which has the advantages of high spectral resolution, low detection limit and non-destructive analysis, provided a new solution to these problems. The principle, characteristics and present application status of mixed laser spectroscopy are introduced, and the application and prospect of this technology in the study of cultural heritage in China are analyzed.
