Gemeinsamer Strahlungspfad zum Ermitteln von Partikelinformation durch Direktbildauswertung und durch Differenzbildanalyse

Device for determining information which is indicative for a particle size and/or a particle shape of particles in a sample, wherein the device comprises an electromagnetic radiation source for generating electromagnetic primary radiation, an electromagnetic radiation detector for detecting electromagnetic secondary radiation which is generated by an interaction of the electromagnetic primary radiation with the sample, and a determination unit which is adapted for determining the information which is indicative for the particle size and/or the particle shape based on the detected electromagnetic secondary radiation, wherein the determination unit is adapted for selectively determining the information firstly by means of an identification and a size determination and/or a shape determination of the particles on a detector image which is generated from the electromagnetic secondary radiation, and/or for determining the information secondly from temporal changes of the electromagnetic secondary radiation between detector images which are generated at different detection points in time.
