Abstract
Plenoptic photography was first introduced by the French Nobel Prize Gabriel Lippmann in 1908 [1] under the name "integral photography". Unlike conventional imaging systems where only the impact position of photons is recorded, a device based on plenoptic technology also records their initial direction of propagation, all the information about the incident light is therefore accessible. This property allows to obtain images with unusual properties such as the possibility to refocus a blurry photo after the picture has been taken or to have an extended depth of field without reducing the aperture of the lens and thus degrading the photometric balance [2]. The opportunity to correct the objective’s aberrations by digital post-processing has also been demonstrated [2].
