光声光谱技术是近年来基于光声效应而发展起来的一种研究材料吸收光谱技术,它能够分析不透明样品和高散射样品,国际上已广泛应用于物理、化学、生物学(特别是分子和亚分子生物学)、医学、非线性光学、工程材料科学,环境科学以及生命科学某些领域的研究。它与传统吸收光谱技术相比具有独特的优点,不但灵敏度和分辨率高,而且适用范围广,它所检测的物质不拘形状,也不需进行予处理,对固体、液体、气体、半导体、粉末、胶状体、悬
Photoacoustic spectroscopy is a material absorption spectroscopy technique developed based on photoacoustic effect in recent years. It can analyze opaque samples and high-scattering samples. It has been widely used in physics, chemistry, biology (especially molecules and Sub-molecular biology), medical, nonlinear optics, engineering materials science, environmental science and life sciences. Compared with the traditional absorption spectroscopy, it has the unique advantages of not only high sensitivity and high resolution, but also wide range of applications. It detects substances in any shape without pretreatment, and has the advantages of solid, liquid, gas, semiconductor, , Gel, hanging
