Abstract

The accuracy of aerosol particle size measurement based on light scattering from single particles depends strongly on the scattering angular range and particle refractive index. The particle size determination suffers frequently from multi-valuedness. Based on the Mie theory of light scattering, light collection angles allowing single-valued aerosol measurement were identified and utilized to design a new optical system with dual light scattering angular ranges. The light collecting optics is located co-axially in the forward (10–30°) and backward (150–170°) direction with reference to the illumination beam and allows a simultaneous measurement of both scattered light fluxes. We found that a weighted superposition of these light fluxes results in monotonically increasing response characteristics versus particle size. In this contribution we analyze the performance of the dual optical system in the particle size range from 0.1 up to 10 μm in diameter and show its capability for an accurate particle sizing and an assessment of the complex refractive index of aerosols.
