Abstract
Single suspended particle detection and recognition are tasks of significance in the context of both biomedical science and environment monitoring. In this work, we develop a system which is capable of both fluorescence and polarization real-time measurement for single suspended particle in the air. In our system, laser of 523nm is generated in light source and adjusted to light sheet in the detection area. Suspended particles fly through detection area and we real-time collect signals on both scattering, fluorescence and polarization channels for each particle. Our system provides the ability for further research on the airborne transmission route for pathogen and real-time detection of toxic pollutants in aerosol which usually emitting fluorescence for specific wavelength laser exciting.
