| 摘要 |
<p>A bioaerosol measurement system receives air having entrained particles of an aerosol. It analyzes these particles and drying these particles and illuminates them. Fluorescence spectra of the particles are determined. The particles are also illuminated with polarized light, amount and polarization of backscattered light is determined. A particle size distribution of the particles is also determined. Measured fluorescence spectra, backscatter data, and particle sizes are used to classify the aerosol. In embodiments, hygroscopicity of the particles is also determined and used to help classify the aerosol. In embodiments, the classifying is done by using a neural network previously trained with data representative of a variety of aerosols.</p> |
