Three-Dimensional Particle Image Velocimetry Using a Plenoptic Camera

  title={Three-Dimensional Particle Image Velocimetry Using a Plenoptic Camera},
  author={Kyle P. Lynch and Tim Fahringer and Brian S. Thurow},
A novel 3-D, 3-C PIV technique is described, based on volume illumination and a plenoptic camera to measure a velocity eld. The technique is based on plenoptic photography, which uses a dense microlens array mounted near a camera sensor to sample the spatial and angular distribution of light entering the camera. Various algorithms are then used to reconstruct a volumetric intensity eld after the image is taken, and cross-correlation algorithms extract the velocity eld from the reconstructed… CONTINUE READING
