Perfectly Diffuse Reflector
</dt>
A body that reflects radiant energy in such a manner that the reflected
energy may be treated as if it were being emitted (radiated) in accordance
with Lambert
law. The radiant intensity reflected in any direction from a unit area of
such a reflector varies as the cosine of the angle between the normal to the
surface and the direction of the reflected radiant energy.
