Light Extinction In Polydisperse Particulate Systems, Lee W. Casperson
Light Extinction In Polydisperse Particulate Systems, Lee W. Casperson
Electrical and Computer Engineering Faculty Publications and Presentations
Analytic methods are developed for determining the attenuation characteristics of light beams propagating through ensembles of scattering particles including those with complex index of refraction. The methods are applicable to a wide range of practical particulate systems, and the results are expressed explicitly in terms of elementary functions. Propagation through fog and clouds is considered as an example, and it is found that absorption by the liquid lengths. water in such ensembles affects strongly the extinction for ir wave-lengths
Single Particle Scattering With Focused Laser Beams, Lee W. Casperson, Cavour W. Yeh
Single Particle Scattering With Focused Laser Beams, Lee W. Casperson, Cavour W. Yeh
Electrical and Computer Engineering Faculty Publications and Presentations
A scattering technique is described in which the incident laser beam is tightly focused to isolate the effects of a single particle. In this way the individual particles may be studied in their natural environment, and experiments with latex spheres are in agreement with the theory.
