Lisäheijastelua

Lisäheijastelua refers to the phenomenon of secondary reflections in optics and physics. It describes light that reflects off a surface more than once. While the primary reflection is the direct bounce of light off an object, lisäheijastelua accounts for light that then bounces off other surfaces or back onto the original surface, contributing to the overall illumination or perceived brightness of a scene.

This effect is particularly relevant in scenarios involving multiple reflective surfaces, such as in a mirror maze or when light interacts with complex architectural structures. In photography and cinematography, lisäheijastelua can influence the mood and depth of an image, sometimes creating unwanted glare or, conversely, enhancing subtle details. In scientific contexts, understanding lisäheijastelua is crucial for accurate light transport simulations, surface analysis, and the design of optical instruments. It is a factor in how we perceive color, texture, and the spatial relationships between objects in illuminated environments. The intensity and color of lisäheijastelua depend on the properties of the intervening surfaces, including their reflectivity and spectral characteristics.
