Abstract
A polarization plenoptic camera that can acquire the polarization information of reflected light from an object in a single shot; i.e., in real time, to avoid issues such as motion blur and also avoid the additional system complexity that derives from mechanical scanning of a polarizer. The camera includes a polarization-sensitive focal plane array, a first microlens array having a pitch that is equal to a pitch of the pixel array; and either a second microlens array having a pitch that is greater than the pitch of the pixel array, a coded aperture mask, or a second microlens array and a coded aperture mask. A method for obtaining a plenoptic image of an object scene is disclosed.
Claims11
A plenoptic imaging apparatus, comprising:
- a polarization-sensitive focal plane array characterized by an array of pixels, in a division-of-focal plane architecture;
- a first microlens array disposed adjacent an object side of the pixel array, having a pitch that is equal to a pitch of the pixel array;
- and
- at least one of a second microlens array disposed at a fixed distance from the object side of the pixel array, having a pitch that is greater than the pitch of the pixel array, a coded aperture mask disposed at a fixed distance from the object side of the pixel array, and a second microlens array disposed at a fixed distance from the object side of the pixel array and a coded aperture mask disposed at a fixed distance from the second microlens array.
A method for obtaining a plenoptic image of an object scene, comprising:
- providing a plenoptic imaging apparatus including a polarization-sensitive focal plane array in a division-of-focal plane architecture;
- obtaining a single-shot measurement of a full Stokes vector at a plurality of spectral bands.
