摘要: Abstract The lunar surface reveals a sharp opposition effect, which is to be explained by the shadowing and coherent backscattering mechanisms. Generalizing radiative transfer theory via Monte Carlo methods, we are carrying out studies of in regolith-like scattering media. We have also started systematic laboratory measurements structural simulators regolith. SMART-1 AMIE D-CIXS/XSM experiments provide us unique opportunity for simultaneous multiwavelength study regolith close opposition, since spacecraft will pass over several different types at zero phase angles. Results our theoretical investigations can used as basis interpret experiments. In particular, it seems possible estimate regional variations particle volume fraction their size. A short review observational, experimental works presented here.
