Abstract
A plenoptic camera including an optical system receiving light issuing from an object field in which there is an object space intended to be processed via the camera. A matrix photosensitive sensor is composed of pixels arranged in rows and columns and such that each pixel receives the light of a single light ray via the system. The light rays, each associated with their pixel, form intersections in the object space, and the optics are configured so as to minimize the greatest distance between any point of the object space and the closest of the intersections of these light rays. Optical elements are aligned and arranged in rows and columns parallel respectively to the rows and columns of the matrix sensor, forming the intersections in the object field, the distances separating the rows and/or columns being irregular.
