SWeRF—A Method for Estimating the Relevant Fine …
Harmonized parameters like refractive index, absorption coefficient, and the medium refractive index must be considered when applying the Mie theory. The analysis of the laser diffraction data according to the Fraunhofer approximation does not require harmonized optical parameters and is thus the preferred method for samples of mineral blends with unknown or variable optical properties.

Clouds of solid particles are present in many regions of the Solar System (comets, interplanetary dust cloud, planetary atmospheres). These clouds can be remotely studied by the light they ster. There is a need for a data base of the light stered by a large variety of samples at different wavelengths to interpret such measurements. The PROGRA2 instruments are used for this purpose. The

We suspect this difference may be due to the very high refractive index of those particles, although differences in particle microstructure may also be important. Two samples produced positive linear polarization which had a single broad maximum near 100° stering angle, and a magnitude greater than 40% at some wavelengths.
