Mie theory, of light scattering

Other measurements important to visual air quality are pollutant related, i.e., the size distribution, mass concentration, and number concentration of airborne particles and their chemical composition. From the size distribution, the Mie theory of light scattering can be used to calculate the scattering coefficient (20). Table 14-2 summarizes the different types of visual monitoring methods (21).

Two theories dominate the theory of light scattering the Fraunhofer and Mie. In the former, each particle is treated as spherical and essentially opaque to the impinging laser light. The... 

Since the classic paper by Mie [159] or even the papers by Clebsch [37] and Lorenz [146] there is a permanent preoccupation in light scattering theory. Mie was interested in the varied colors exhibited by colloidal suspensions of noble metal spheres, but nowadays, the theory of light scattering by particles covers a much broader and diverse field. Particles encountered in practical applications are no longer considered spherical they are nonspherical, nonrotational symmetric, inhomogeneous, coated, chiral or anisotropic.

Most commercial instruments use optical models in tlicir analysis software that arc based on Mie scattering theory or Fraunhofer diffraction. Mie theory provides a complete soluuon to the problem of light scattering by a sphere, including the eiTccis of transmitted and absorbed light. On the other hand, the Fraunhofer dif-...
