The Basic Vocabulary and Concepts of Light Scattering

The subject of studying the size, shape, and the constitution of a population of fineparticles from their diffraction patterns is complex. Many books have been written on the topic, see for example references 3, 4, 5, 6, and 7. International confer- 

Oestnictlve Interference Two waves arrive one haif wavelength out of phase 

Absorption reduction of intensity of a light beam traversing a medium throughenergy conversion in the medium. 

Complex Refractive Index (m) refractive index of a fineparticle relative to that of the medium, consisting of a real and an imaginary (absorption) part. 

Deconvolution mathematical procedure whereby the size distribution of a fineparticle ensemble is inferred from measurements of the scattering pattern produced by the ensemble.
