WebBecause the lateral resolution of light-field imaging is much better than the axial resolution, by fusing the two views, the high lateral resolution of view 2 can enhance the axial resolution of view 1 up to view 1′s lateral resolution, providing an isotropic resolution for LF-PIV. 2.1. Isotropic light-field image reconstruction To compare with the results of distributed object points, a USAF-1951 transmission resolution target was used. The target was tilted with respect to the system, and the investigated area was back-illuminated. A raw image was captured, as shown in Fig. 4a.
