Laser-based volumetric colour-coded three-dimensional particle velocimetry

“…For example, sequenced colour illumination combined with colour imaging has been used in PIV to resolve directional ambiguity [13], phases in twophase flows [14], and for unambiguously colour coding long particle tracks, useful in measuring recycling and turbulent flows [15]. For increasing spatial information in particle velocimetry, two overlapping lightsheets of different colours have been used to obtain 3/2D-3C PIV [16][17][18]. However, as with a similar scheme based on a single monochromatic lightsheet with graded irradiance [6], extraction of the third spatial dimension with these schemes is very sensitive to absolute image intensity, which is practically difficult to control when imaging scattering particles.…”

In-plane determination of 3D-velocity vectors using particle tracking anemometry (PTA)

“…More straightforward approaches are those of Cenedese et al (1989) and of Nino et al (1992) using two light-sheets with different colours and Dinkelacker et al (1992) Correspondence to: W. Stolz intensity-graded light-sheet. New approaches use the defocusing of imaged objects (particles) for either the determination of particle tracks of single particles in a large measuring volume (Willert and Gharib 1992 ) or the in-plane determination of the three flow velocity vector components (Stolz and KShler 1992).…”

Colour-coded tomography in fluid mechanics

“…For quantitative analyses of whole fields, measuring systems such as PIV [4][5][6][7] or PTA [8][9][10] can provide sequences of flow data in successive frames. To account for the third velocity component in the plane under consideration, extensions of these techniques have been proposed [11][12][13]. To analyse whole flow volumes, systems based on stereoscopy or multicamera detection [14][15][16][17] and tomography have been introduced.…”
