Plano-concave mini-lens array for plenoptic imaging applications

An array of plano-concave mini-lenses is designed to realize a particular version of Light Field camera known as Plenoptic Camera 1.2. The Delano diagram related to the on-axis optical channel of such a camera is computed to show its retro-focus behavior and it is compared with the Delano diagrams of the Galilean and Keplerian configurations.
