Time and Space Resolved Characterization of Nanoparticles
PhD Student: Georg Brunnhofer
Supervisor: Alexander Bergmann
Research Area: xy
The dissertation aims to realize and validate a multi-physical sensorsystem to characterize nano particles with respect to particle density, particle size, particle velocity and particle wettability. This characterization is targeted to be performed in a time scale < 1s in real time.
simulating, realizing and optimizing a laser optical setup for in-situ detection of the holographic image of the dispersing phase,
identifying evaluation algorithms (e.g.: Find Circle/Elliptic Algorithm, Computer Vision Algorithm, Velocity Determination, ...), developing (further) and implementing in e.g.: MATLAB/LabVIEW and assessing systematically,
implementing these algorithms into real time sensorsystems (e.g.: NI cRIO Hardware Platform) for the detection of particle density, particle size, particle velocity and wettability,
validating the sensor system using model aerosols such as soot, NaCl, DOPS and referencing equipment like Condensed Particle Counter, Scanning Mobility Particle Sizer (SMPS), static light- or X-ray scattering.
