一、概述光声光谱是近几年复兴起来的一种先进光谱技术,自一八八○年Bell发现了固体样品的光声效应以来,由于缺少灵敏的微音器及较强的单色光源,应用受到了限制。近年来,随着可调谐激光器、高灵敏微音器的出现以及
I. Overview Photoacoustic spectroscopy is an advanced spectroscopic technique that has been revived in recent years. Since Bell discovered the photoacoustic effect of solid samples in 1880, due to the lack of sensitive microphones and strong monochromatic light sources , The application has been limited. In recent years, with the advent of tunable lasers, highly sensitive microphones as well
