| Summary: | The non-spherical particle sizing is very important in the aerosol science,
and it can be determined by the light extinction measurement. This paper
studies the effect of relationship of the size range and aspect ratio range
on the inversion of spheroid particle size distribution by the dependent mode
algorithm. The T matrix method and the geometric optics approximation method
are used to calculate the extinction efficiency of the spheroids with
different size range and aspect ratio range, and the inversion of spheroid
particle size distribution in these different ranges is conducted. Numerical
simulation indicates that a fairly reasonable representation of the spheroid
particle size distribution can be obtained when the size range and aspect
ratio range are suitably chosen. |
