Subsurface scattering.

If λ is the wavelength of neutrons, and θ is the scattering angle, the scattering variable is defined as Q = 4 π λ sin θ 2. The value of Q usually ranges between 0.001 Å –1 and 0.45 Å –1. SANS machines are designed for measurements of the scattering object sizes ranging from 1 to 300 nm.

Dec 26, 2017 · Initial Release. Subsurface Scattering is the effect of light coming in direct contact and interacting with a translucent material or surface and "scattering" at an endpoint. The result of this effect when light interacts with skin is, in most scenarios, a pink-ish translucent effect (hold your hand up to any light and you'll see). Global or indirect illumination effects such as interreflections and subsurface scattering severely degrade the performance of structured light-based 3D scanning. In this paper, we analyze the errors in structured light, caused by both long-range (interreflections) and short-range (subsurface scattering) indirect illumination. The errors depend on the …
