Abstract
An object of the invention is an image sensor comprising a matrix of pixels, extending along a detection plane, and configured to form an image of an incident light wave propagating in a spectral band along a propagation axis, the image sensor being characterized in that it comprises a mask, formed by opaque elementary masks, extending parallel to the detection plane, between which there extend openings through which the incident light wave can propagate toward the detection plane, the matrix of pixels being divided into:
