虽然上世纪末年已经发现了光声效应,直到本世纪七十年代起,光声光热技术才与现代激光技术和弱信号检测技术等相结合而开始迅速发展。由于这种技术的检测灵敏度高,可测的波谱范围宽,而且在测定物质物理、化学特性等方面成功地解决了不少其他方法不易解决的难题,因而在物理、化学、生物、医学、环境科学和材料科学等许多领域中得到了广泛而有效的应
Although the photoacoustic effect has been found in the last century, the photoacoustic photothermal technology began to develop rapidly until the seventies of this century with the combination of modern laser technology and weak signal detection technology. Due to its high detection sensitivity, wide range of measurable spectra, and the successful resolution of many other methods in the determination of physical and chemical properties of the material, the technology is widely used in physics, chemistry, biology, medicine and the environment Science and Materials Science and many other areas have been widely and effectively applied
