Measurement of Quantitative IR Properties of Single Aerosol Particles With Emphasis on Biological and Chemical Stimulants

摘要

The angular scattering pattern of theta and Phi is sensitive to a particle's morphology (size, shape, refractive index, and surface structure). We have demonstrated that the angular pattern of the scattered light is also dependent on the absorptive pan of the particle. Using numerical simulations, based on Mie's theory, we found that absorption leads to an increase in the peak-to-valley ratio in the angular scattering pattern.
