One- <strong>and</strong> two-dimensional diffusers
Types of diffusers • Geometric diffusers – Simple curved surfaces – Irregular geometric structures – Periodic geometric structures – Mixture of absorbing <strong>and</strong> reflecting materials • Mathematical diffusers – MLS (Maximum Length Sequence) diffusers – QRD (Quadratic Residue Diffusers) – PRD (Primitive Root Diffusers) – Fractal diffusers – Curved diffusers
