There are fundamentally two types of optical scattering for diagnostics and monitor-
ing: elastic and inelastic. The elastic scattering can be described using Mie theory (or
Rayleigh scattering for particles small compared to the wavelength) in which the
intensity of the scattered radiation can be related to the concentration, size, and shape
of the scattering particles. The inelastic scattering in which the polarization of the
particle is not constant can be described as Raman scattering. Fluorescence is also
inelastic.
用于诊断和监控的光散射主要有两种:弹性散射和非弹性散射.弹性散射可以运用米氏散射理论(或波长较小的瑞利散射)进行描述,米氏理论认为,散射线的强度可能与散射粒子的密度、体积、形状有关.粒子极性不恒定的非弹性散射可以运用拉曼散射进行描述.荧光也是非弹性的.
