研究目的
Investigating the spontaneous light scattering under conditions where the optical properties of the material system are unmodified by the presence of the incident light beam.
研究成果
Spontaneous light scattering is profoundly modified when the intensity of the incident light is sufficiently large to modify the optical properties of the material system. The chapter sets the foundation for understanding various light-scattering processes and their characteristics under different conditions.
研究不足
The analysis assumes a completely homogeneous medium for scattering only in the forward direction and does not account for modifications in the optical properties of the material system by the incident light beam.
1：Experimental Design and Method Selection:
The chapter describes spontaneous light scattering and its modification under intense incident light. Theoretical models include the interaction of light with vibrational modes of molecules (Raman scattering), sound waves (Brillouin scattering), and nonpropagating density fluctuations (Rayleigh scattering).
2：Sample Selection and Data Sources:
The analysis considers a completely homogeneous medium and the effects of fluctuations in the optical properties of a material medium.
3：List of Experimental Equipment and Materials:
Not explicitly mentioned in the provided text.
4：Experimental Procedures and Operational Workflow:
The text discusses the setup for observing spontaneous light scattering and the conditions under which scattering occurs, including the role of fluctuations in the optical properties of the medium.
5：Data Analysis Methods:
The analysis involves understanding the spectrum of scattered light, including Raman, Brillouin, Rayleigh, and Rayleigh-wing features, and their relation to physical processes.
