Diffuse reflection refers to the phenomenon that when light encounters a surface, it no longer reflects along its original path, but is scattered evenly in different directions. This phenomenon occurs when light strikes a rough surface or media interface. Unlike specular reflection, diffuse reflection does not create a clear mirror image, but spreads light evenly in all directions.
In diffuse reflection, light interacts with microstructures or irregularities on an object’s surface, causing the light to scatter at various angles. Such diffusion enables light to cover the surrounding area more widely, creating a soft light environment, reducing glare and shadows caused by strong light, thereby providing a more comfortable and uniform lighting effect.
Diffuse reflection is used in various fields, such as using special materials or surfaces in lighting design to achieve a more uniform and soft lighting effect, or using diffuse reflection plates in photography to diffuse light, reduce shadows, and create soft shooting effects. This scattering property allows light to spread and distribute more evenly, helping to improve the visual experience and environmental comfort.
