Validation and comparison of a proposed calibration-free optical (CFO) method for characterization of an axisymmetrical powder stream : research data underlying the article

Jeromen, Andrej (author), Govekar, Edvard (author)

This data set was generated for validation and comparison of a proposed calibration-free optical (CFO) method for a DED powder stream characterization, namely, for particle number density distribution determination. The CFO method data consist of example captured images and the number of detected particles (NDP) matrices. Those were validated against the results of the weighing powder stream characterization method and compared to the usual Mie scattering-based optical characterization method, which data are also included in this set.
