摘要：
We describe a 3D screen design and a methodology for using such screens to determine scatterer-particle parameters, and propose a technique for the use of 3D screens in the measurement of non-normalized moments (up to 6th order). We show that the non-normalized moments can be determined from the attenuation in light power produced by a series of 3D screens; the number of screens determines the order of the moment to be measured. The non-normalized moments provide information on the equivalent cross-section of the scatterer particles and the distribution function of particles over cross-sectional area. © 2018, Springer Science+Business Media, LLC, part of Springer Nature.
