Abstract : In this report a comparison has been made between (1) the computed angular scattering coefficient for a polydisperse cloud of small spherical (Mie) particles and (2) the measured angular scattering coefficient for a polydisperse cloud of irregular, randomly oriented (Mie) particles fitting the same distribution function and having the same material properties. The comparison has been made for eight separate wavelengths covering the photopic range. Four particle materials were studied: aluminum oxide, carbon black, silicon dioxide and talc. These materials had median volume diameters in the range of 0.1 to 1.0 microns according to the manufacturers specifications. (Author)
