A plenoptic imaging device is described including a micro-lens array placed between a main lens and a photosensor. The micro-lens array has a plurality of micro-lenses each configured to project a micro-image onto the photosensor, the main lens covering a central field-of-view of the scene according to capture axis. The plenoptic imaging device includes multi-faceted optical means structure having at least two facets and placed in a plane adjacent to the aperture diaphragm plane and centered on the main optical axis, each facet being configured to angularly rotated the capture axis with respect to the main optical axis so as to capture a rotated field-of-view from the central field-of-view, and so that the captured rotated field-of-views form an expanded field-of-view covering the central field-of-view.
