Figure 3. Manipulation of the level of scattering diffusion by controlling the super-unit-cell size of the controllable random surface.

(a–c) The mixed coding patterns when the weight numbers w of the three random coding patterns are set as w₁ = [0 1 0 0 0 0], w₂ = [0 0 1 0 0 0] and w₃ = [0 0 0 1 0 0]. (d–f) The corresponding 3D scattering patterns. (g–i) The corresponding plots for the probability clouds of the random scatterings.
