Abstract
A plenoptic, or light field, imaging enables the reconstruction of the light field, and therefore of a 3D scene, from a single camera through computational imaging. The plenoptic approach is an improvement to Fourier integral microscopy, or FIMic, to macroscopic imaging. The plenoptic imaging scheme offers better spatial resolution and simpler calibration and many generic computational reconstruction schemes. The plenoptic system does not require a complex customization of a camera, but instead relies on the design of a camera objective, which greatly reduces the complexity and cost of the scheme and simplifies its deployment to many cameras.
Claims17
A plenoptic apparatus for imaging an object, comprising:
- a photosensitive detector;
- and
- an objective lens having a front element group, a rear element group, an aperture at a back focal plane of the front element group, and a lens array co-located with the aperture to sample the Fourier plane, the lens array positioned at a back focal of the front lens group of the objective, wherein the objective lens is positioned to image the object onto the photosensitive detector.
An apparatus, comprising:
- a photosensitive detector;
- and
- an objective having a front element group, rear element group, aperture substantially at a Fourier plane, and a specialized elements co-located with the aperture to sample the Fourier plane, the lens array positioned at the back focal of the front lens group of the objective, wherein the objective lens is positioned to image an object onto the photosensitive detector.
