Binary amplitude diffusion

Binary Amplitude Diffusors are a different method of providing diffusion. Like reflection phase gratings they also rely upon mathematical sequences but rather than having wells of varying depths, they employ a sequence of surfaces that alternate reflection and absorption. This binary (reflect OR absorb) … See more Diffusion is an enigma.
