The reflection of a beam of light during which the light beam scatters in a wide range of directions, as described on this page of this module. Also called specular reflection, it occurs when light is reflected by a rough surface such as a classroom wall. Diffuse reflection is the opposite of total reflection, which is NOT the same as total internal reflection.
the reflection of rays from a rough surface. The reflected rays do not leave at set angles, so they are scattered
When light reflects in many different directions, after all the incident rays are parallel, or irregular reflection.
The type of reflection obtained from a relatively rough (in terms of the wavelength of the radiation) surface, in which the reflected rays are scattered in all directions.
A bar code verification term. The component of reflected light that emanates in all directions from the reflecting surface (as opposed to the focused light of the scanner laser reflected back to the scanner).
Takes place when different parts of a beam incident on a surface are reflected over a wide range of angles in accordance with Lambert's law. The intensity will fall-off as the inverse of the square of the distance away from the surface and also obey a cosine law of reflection.
Change of the spatial distribution of a beam of radiation when it is reflected in many directions by a surface or by a medium.
parallel incident rays that are reflected in various directions from a rough surface.
1. The change in the direction of radiation into all directions after encountering a rough surface. Compare specular reflection. 2. Term frequently applied to the process by which solar radiation is scattered by dust and other particles suspended in the atmosphere. 3. Reflection by a diffuse reflector.
Diffuse reflection is the reflection of light from an uneven or granular surface such that an incident ray is seemingly reflected at a number of angles. It is the complement to specular reflection. If a surface is completely nonspecular, the reflected light will be evenly spread over the hemisphere surrounding the surface (2×Ï€ steradians).
