I am confused: What exactly is the difference between optical scattering and optical reflection?

To me, both terms are distinguished by where we place the observation plane.

Reflection: Observation plane is normal to substrate -> we record only normal reflection

Scattering: Observation plane is a sphere -> we record reflection in all possible directions

Often, one can either compute reflection or scattering, but isn't scattering just a more general reflection?

  • $\begingroup$ They're very different. Have you done any research? You should have a look at en.wikipedia.org/wiki/Scattering Sunlight scatters in the atmosphere. If it were reflected, we wouldn't exist. $\endgroup$ – FGSUZ Jan 5 at 10:47
