Diffusion

The scattering of directional incident beam of light in most directions by reflection from a roughened surface or by passage through a translucent material.  An opalescent diffusion screen such as in a light box helps produce an evenly illuminated surface.  A perfect diffuser or lambertian surface is one that is seen with uniform luminance irrespective of viewing direction.
