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 WebKeywords: Light Field, Plenoptic, 3DPTV ABSTRACT Plenoptic 1.0 cameras have already been investigated as a means for performing 3DPIV. Plenoptic 2.0 cameras have an enhanced in-plane resolution, but are limited to less dense particle fields by their depth-detection method, and are thus less appropriate for 3DPIV.
