Process and apparatus for the capture of plenoptic images between arbitrary planes

A process and an apparatus are described for the plenoptic capture of photographic or cinematographic images of an object or a 3D scene (10) of interest, both based on correlated light emitting source and correlation measurement, along the line of "Correlation Plenoptic Imaging" (CPI). A first image sensor (Dɑ) and a second image sensor (Db) detect images along a path of a first light beam (ɑ) and a second light beam (b), respectively. A processing unit (100) of the intensities detected by the synchronized image sensors (Dɑ, Db) is configured to retrieve the propagation direction of light by measuring spatio-temporal correlations between light intensities detected in the image planes of at least two arbitrary planes (Ρ', P"; D'b, D"a) chosen in the vicinity of the object or within the 3D scene (10).
