Hein, M. (author), Wieneke, B. (author), Seemann, R. (author)Micro-PIV (?PIV) uses volume-illumination and imaging of fluorescent tracer particles through a single microscope objective. Displacement fields measured by image correlation depend on all imaged particles, including defocused particles. The measured in-plane displacement is a weighted average of the true displacement with a weighting function W...conference paper 2013

(author), Jeon, Y. J. (author), Chatellier, L. (author), Augereau, L. (author), Tremblais, B. (author), David, L. (author)Classical Particle Image Velocimetry (PIV) uses two representations of the particle image distribution to determine the displacement of the particle image pattern by spatial cross-correlation. The accuracy and the robustness are however limited by the fact that only two representations at t and t +?t are present. Thus, only a first order...conference paper 2013

Sciacchitano, A. (author), Scarano, F. (author), Wieneke, B. (author)The topic of uncertainty quantification in particle image velocimetry (PIV) is recognized as very relevant in the experimental fluid mechanics community, especially when dealing with turbulent flows, where PIV plays a prime role as diagnostic tool. The issue is particularly important when PIV is used to assess the validity of results obtained...conference paper 2013

Schanz, D. (author), Schröder, A. (author), Gesemann, S. (author), Michaelis, D. (author), Wieneke, B. (author)A novel approach to the evaluation of time resolved particle-based tomographic data is introduced. By seizing the time information contained in such datasets, a very fast and accurate tracking of nearly all particles within the measurement domain is achieved at seeding densities comparable to (and probably above) the thresholds for tomographic...conference paper 2013

Sciacchitano, A. (author), Wieneke, B. (author), Scarano, F. (author)A super-resolution approach is proposed for the a posteriori uncertainty estimation of PIV measurements. The measured velocity field is employed to determine the displacement of individual particle images. A disparity set is built from the residual distance between paired particle images of successive recordings. Within each interrogation window...conference paper 2012
