Synchronous detection of multiple optical characteristics of atmospheric aerosol by coupled photoacoustic cavity
文献摘要：
Owing to the influence of sampling loss,cavity difference and detecting source,the multi-optical parameter measure-ment of atmospheric aerosol cannot be detected simultaneously in the same reference environment.In order to solve this problem,a new method of simultaneously detecting the aerosol optical parameters by coupling cavity ring-down spectrom-eter with photoacoustic spectroscopy is proposed.Firstly,the coupled photoacoustic cavity is formed by the organic fusion of the photoacoustic cavity and the ring-down cavity.Secondly,the integrated design of the coupling spectroscopy system is carried out.Finally,the extinction coefficient and absorption coefficient of aerosol are measured simultaneously by the system,and then the aerosol scattering coefficient and single albedo are calculated indirectly.The accuracy of the system is verified by comparing with the data from the environmental quality monitoring station,which provides a new idea for the detection of multi-optical characteristics of atmospheric aerosol.
