Noun
scatterer (plural scatterers)
One who, or that which, scatters.
A Lambertian scatterer will then scatter this light according to the same cosine law as a Lambertian emitter. Source: Internet
For example, if the moon were a Lambertian scatterer, one would expect to see its scattered brightness appreciably diminish towards the terminator due to the increased angle at which sunlight hit the surface. Source: Internet
The fact that it does not diminish illustrates that the moon is not a Lambertian scatterer, and in fact tends to scatter more light into the oblique angles than would a Lambertian scatterer. Source: Internet
