diffuse reflection

The reflection of a light ray by a rough surface in which the angle of reflection is not equal to the angle of incidence. As opposed to specular reflection by a smooth surface in which the angle of reflection equals the angle of incidence. Employed in the analytical technique of reflectometry.

For example, an ideal mirror does not have any diffuse reflection and for this reason the physical surface of the mirror cannot be seen.
As the artificial skin has a rough surface similar to the wrinkles and the skin texture, the pearlescent pigments on the artificial skin show not only specular reflection but also diffuse reflection coming from the roughness of surface.
A gaseous atom can interact briefly with a photon and this can result in diffuse reflection or scattering.
Consequently, the reflection tends to be more concentrated around the specular direction and hence the increase in specular intensity and decrease in diffuse reflection.
