Martin Löffler-Mang • Studied Physics at University of Karlsruhe: Double puls holography, Fourier optics • Doctor Thesis at EBI, Uni Karlsruhe: Spray investigations with laser measuring techniques, (LDV, PDPA, etc. ) • Postdoc at IMK, Forschungszentrum Karlsruhe: Experimental work for precipitation systems, (Radar, Malvern, PARSIVEL, etc. ) • Professor at University of Applied Sciences in Saarbrücken: Optical sensors and metorological applications, (HARE, Nebio. Sens, PDPA, Fly. P, Mini. LDA, etc. )

First idea: Minimized Particle Analyzer (Mini. PA) Based on Mini. LDA, tophat-profile, intensity analysis Measuring Volume = 0. 1 mm 3 Measuring Frequency = 100 k. Hz Particles: Drops and ice crystals Information about: • Particle size • Particle velocity (2 D) • Turbulence

Second idea: Cloud Particle Sensor (Cloud. Sens) Based on enlarged Nebio. Sens Measuring Volume = 100 – 1000 cm 3 Measuring Frequency = 10 k. Hz Particles: Drops and ice crystals Information about: • Particle type • Particle concentration

Groups for collaboration: 1. Simulation of scattered light 2. Clouds in the laboratory 3. Reference measurements
