On the resolution of plenoptic piv
WebFor PIV-related measurements, normally only single wavelength is involved (e.g. λ = 532 nm). In addition, the time information is considered by the form of two images (e.g. double-frame exposure PIV) or multiple images (e.g. time-resolved PIV). The above seven-dimensional plenoptic function can therefore be simplified Web5 de jul. de 2024 · The light field particle image velocimetry (LF-PIV) has shown great potential for three-dimensional (3D) flow measurement in space-constrained applications. Usually, ... T. W. Fahringer, and B. S. Thurow, “ On the resolution of plenoptic PIV,” Meas. Sci. Technol. 27, 084003 (2016).
