Dual wavelength digital holography for 3D particle image velocimetry [PDF]
Journal of the European Optical Society-Rapid Publications, 2015 A multi-exposure digital in-line hologram of a moving particle field is recorded by two different wavelengths and at different times. As a result, during the reconstruction step, each hologram can be independently and accurately reconstructed for each ...

Particle image velocimetry (PIV) uncertainty quantification using moment of correlation (MC) plane [PDF]
Measurement science and technology, 2018 We present a new uncertainty estimation method for particle image velocimetry (PIV), that uses the correlation plane as a model for the probability density function (PDF) of displacements and calculates the second order moment of the correlation (MC ...

Meta-uncertainty for particle image velocimetry [PDF]
Measurement Science and Technology, 2021 Abstract Uncertainty quantification for particle image velocimetry (PIV) is critical for comparing experimentally measured flow fields with computational fluid dynamics results, and model design and validation. However, PIV features a complex measurement chain with coupled, non-linear error sources, and quantifying the uncertainty is ...
