- Fourier Slice Theorem [Bracewell 1956]. The end result is the Fourier Slice Photography Theorem(Section4.2),whichstatesthat in the Fourier domain, a photograph formed with a full lens aper-ture is a 2D slice in the 4D light field. Photographs focused at dif-ferent depths correspond to slices at different trajectories in the 4D space.

- This paper contributes to the theory of photograph formation from light fields. The main result is a theorem that, in the Fourier domain, a photograph formed by a full lens aperture is a 2D slice in the 4D light field. Photographs focused at different depths correspond to slices at different trajectories in the 4D space. The paper demonstrates the utility of this theorem in two different …
