Based on the particle scattering photography approach proposed in Part I, a series of experiments are conducted in this work to validate the theoretical analysis, demonstrate the application features qualitatively and quantitatively, and evaluate the measurement errors. As expected, aided respectively by scattering light of four representative oxide powders (TiO2, Al2O3, CuO, and SiO2), the grayness differences between the bubbles and continuous phases in all images are improved with different extents, and especially the TiO2 particles perform the best. Grayness differences present a unimodal distribution with TiO2 concentration variation, and the optimum concentration is 7.3 mg/L. This particle scattering approach is proven to be more accurate, with an average error of <5% for the bubble size, in comparison with that of the reflector-aided method (>20%).
