Abstract
In the last few years renewed attention has been paid to the study of light scattering from random media. This due to the recent discovery of a phenomenon that dynamic light scattering from a fluctuating random medium may produce shifts of spectral lines, even when the source and the scattering medium are at rest relative to the observer. It has also been demonstrated that a similar phenomenon may occyr in static light scattering from spatially random media without dynamic fluctuations.By the well-known analogy between the processes of scattering and radiation, these phenomena in scattering are found to be closely related to the correlation-induced spectral changes in the coherence theory which are often referred to as the Wolf effect. In this paper some recent developments are reviewed on research regarding the phenomena of changes in the attempts for elucidating the effects of multiple scattering on these phenomena.
