<objectives>In this course, students will deepen their knowledge of particle measurement technology (Based on the &quot;Lasermesstechnik&quot; course), especially Laser Doppler Particle Analysis (PDPA). After successfully completing this course, students will thus have mastered the statistics of particle size distributions, the theoretical basics of PDPA and know how to handle a modern PDPA system. They will be able to independently measure and interpret a nozzle spray with PDPA. </objectives>
<content>Principles of particle measurement technology:
+ Identifying particles
+ Representing quantity distributions
+ Sets and distribution functions
+ Converting distributions, moments
+ Distribution parameters
+ Approximation functions
+ Dimensional analysis
+ Methods for measuring particle size
+ Sampling, sample splitting
+ Light scattering

Introduction to and theory of PDPA:
+ Interference fringe model
+ Doppler model
+ Frequency shift and multi-components
+ Qualitative and quantitative PDPA model
+ System design
+ Examples of use
+ Current density and concentration

Practical course in the OML lab:
+ Laser power and wavelengths
+ Laser safety
+ Operating the software
+ Independent spray analysis</content>
