Paper Abstract

The backscattering coefficient and intensities of soot particles were calculated using Mie scattering theory for the different incidences laser wavelengths and particle radii with complex refractive index also talked into consideration. The calculation results indicated that at a scatter angle of 180°,the backscattering intensities can go up by 30% of forward scattering intensities at different radii of particles if the resource laser wavelength is properly selected. This conclusion provides a theoretical basis for the selection of laser sources and detector aiming at enhancing Signal Noise Ratio.
