 Forced Rayleigh scattering

Forced Rayleigh scattering (FRS) is a technique used to analyze the properties of materials by probing them with light. It is an extension of the classical Rayleigh scattering phenomenon, which refers to the scattering of light by small particles. In classical Rayleigh scattering, the incident light interacts with particles in a medium, leading to scattered light whose characteristics depend on the size, shape, and composition of those particles.
