How to estimate the necessary sample volume ?

Cold Surface Spectroscopy Facility
The necessary sample volume to fullfill the photometric constraints mainly depends on several parameters: grain size (diameter) , Dg porosity, P reflectance level at the most transparent wavelength, Rm maximum angle of emergence angle of observation, e_max range of azimut of the observations
We use the following rules of thumb (validated on several typical samples) to determine the minimum depth, d, and the minimum diameter, D, of (…)
