Polarimetric camera

A polarimetric camera, including an optical system and an image sensor:

• the optical system, having a principal optical axis, being adapted to form, on the image sensor, at least N spatially distinct images of a scene to be imaged, at the rate of one image per polarization state, with N greater than or equal to 2, N being a predefined number of polarization states, and including:
• a polarization separator adapted to divert the incident light beams coming from the scene to be imaged according to the N polarization states, the optical system then having at least N exit pupils at least partly offset in pairs orthogonally to the principal optical axis;
• the image sensor including a plurality of detection pixels each comprising a photodetector;
• the detection pixels being distributed in at least N subsets of pixels, each associated with an exit pupil, and each intended to receive the incident light beams according to the polarization state of the associated exit pupil;
• wherein the image sensor includes at least N angular filters located between the optical system and the photodetectors, each angular filter being adapted to transmit, to a subset of pixels, the incident light beams coming from the associated exit pupil, and to at least partly filter the incident light beams coming from the other exit pupil or pupils.
