  • Holographic detection and characterization of large impurity particles in precision slurries
    Patent number: 10641696
    Abstract: Impurities within a sample are detected by use of holographic video microscopy. The sample flows through the microscope and holographic images are generated. The holographic image is analyzed to identify regions associated with large impurities in the sample. The contribution of the particles of the sample to the holographic images is determined and the impurities are characterized.

  • HOLOGRAPHIC CHARACTERIZATION USING HU MOMENTS
    Publication number: 20190234853
    Abstract: Holographic microscopy analysis system and methods for determining morphology of a particle in a sample. A bright-field reconstruction image is generated from a recorded hologram from a holographic microscopy system. Morphology of particles imaged by the system may be determined. Hu moments are calculated, either from the hologram or from the bright-field reconstruction, or both, to provide an indication of morphology.
