Abstracts
This paper offer the characteristics for the detection and classification of biological and non-biological aerosol
particles in the air by using laser-induced-fluorescence (LIF) based Bio-aerosol Detection System (BDS). The BDS is
mainly consist of an optical chamber, in-outlet nozzle system, 405 nm diode laser, an avalanche photo detector (APD)
for scattering signal and photomultiplier tubes (PMT) for fluorescence signals in two different wavelength range ;¡¡F1,
510-600 nm and F2, 435-470 nm. The detection characteristics, especially ratio of fluorescence signal intensity were
examined using well-known components : polystylene latex (PSL), fluorescence PSL, 2 § of SiO2 micro sphere, dried
yeast, NADH, ovalbumin, fungicide powder and standard dust. The results indicated that the 405 nm diode laser-based
LIF instrument can be a useful bio-aerosol detection system for unexpected biological threaten alter in real-time to
apply for dual-use technology in military and civilian fields.
