起源于十九世纪的实验光声探测光谱学目前已经重新复活,并已进入实用领域,从探测小量的污染性气体到了解宇宙空间中分子的物理状态;从探测气体和液体直到研究固体表面及次表面的微观结构。光声技术的高灵敏度和极好的适应性,使它在物理、化学、电子学、生物学、医学、环保检测及国防军事等多种领域中得到了应用。
The experimental photoacoustic probe spectroscopy, dating back to the nineteenth century, has now been revived and has entered practical use, ranging from the detection of small quantities of polluting gases to the physical states of molecules in space; from the detection of gases and liquids to the study of solid surfaces And subsurface microstructure. The high sensitivity and excellent adaptability of photoacoustic technology make it applied in various fields such as physics, chemistry, electronics, biology, medicine, environmental testing and defense and military affairs.
