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.
