Studies on lunar regolith samples and high-porosity structural models confirm that lunar surface materials exhibit unique optical scattering behaviors, such as a strong opposition effect, when illuminated from overhead angles.
The retrieved literature (specifically papers 4 and 9) directly discusses the optical scattering properties and opposition effects of lunar regolith and its high-porosity structures under specific illumination angles. None of the papers refute this, resulting in a supported balance verdict.
