The laser detector of bio-aerosols

In the paper we describe a new construction and preliminary laboratory tests of airborne particle flow detector. The device is designed for continuous monitoring of biological particles in ambient air. The scattering and fluorescence signals from each particle are detected simultaneously. The device uses 375 nm laser for fluorescence excitation. The luminescence is measured with three broad bands. Principal Component Analysis was applied for data analysis. It has been demonstrated proper classification between various biological aerosols.
