Volume Scattering

  Volume scattering describes the phenomenon where light interacts with particles within a medium, resulting in scattering. This occurs in various substances, such as fog, clouds, water, glass, and other materials. Studying volume scattering is crucial for understanding light-matter interactions, especially in fields like optics, atmospheric science, biomedical engineering, and material science. Research on volume scattering has significant implications for a variety of fields, including computer graphics rendering, material characterization, lighting design and technology, illumination engineering, and beyond. Rayzen provides scientists and engineers with a specialized tool to better comprehend and simulate the interactions between light and materials. Using non-sequential optical simulation software is essential for volume scattering simulation for the following reasons:

1. Accuracy: Rayzen accurately models and computes parameters in volume scattering models, ensuring consistency between theoretical predictions and real-world results.
2. Efficiency: By utilizing parallel computation, Rayzen can process large-scale simulations and calculations in a short time, significantly improving research and development efficiency.
3. Visualization: The preview scene functionality in Rayzen allows for an intuitive understanding of light-material interactions, enabling precise analysis and optimization of scattering phenomena.
4. Interdisciplinary Applications: Volume scattering models are applicable not only in atmospheric and life sciences but also in fields like physics, chemistry, and engineering. The broad capabilities of GMPT simulation software offer immense potential for future applications.

  This study uses Rayzen optical system simulation software to simulate volume scattering. Rayzen, based on low-discrepancy sequence Monte Carlo methods, non-sequential forward ray tracing, and rapid intersection algorithms, analyzes particle types, mean free paths, anisotropy parameters, and material properties. It evaluates the effects of these parameters on light propagation, refraction, reflection, and scattering in complex optical systems. The software is widely applied in stray light analysis for optical components and optoelectronic modules, illumination distribution in lighting systems, and research in biomedical science, materials science, and meteorology.

  This topic demonstrates the simulation of illuminance distribution for Henyey-Greenstein volume scattering using Rayzen, showcasing the process of constructing scattering particle attributes, analyzing scattering curves, and evaluating illuminance distribution. This aids in understanding the capabilities and operations of Rayzen software, delving into the principles of optical simulation, and supporting further analysis of material properties and light propagation paths.
