Claim 0:
1. A differentiation system for differentiating microscopic particles, the system comprising:
an input device configured to receive an interference pattern representative of a microscopic particle in suspension, the interference pattern corresponding to holographic images acquired with a digital in-line holographic microscope from the microscopic particle in suspension, wherein the digital in-line holographic microscope is configured to capture depth information during acquisition of the interference pattern;
holographic image data processing logic configured to derive a Fourier spectrum of the interference pattern by performing a Fourier transform; and
a microscopic particle recognizer configured to determine characterization features from the Fourier spectrum of the interference pattern for characterization of the microscopic particle, wherein the characterization features include rotationally invariant features.
