RÉSUMÉ
We study the dependence of the reflectance spectra of regolith-like surfaces on the phase angle. A computer model based on the ray optics approximation is used. Our calculations reveal a strong non-monotonous dependence of the spectral slopes on the phase angle. Changing observation geometry also influences the depth of the absorption bands. We also calculate the phase angle distribution of the average path lengths <L> that rays pass through in the medium between the points of entrance and emergence.
