TLDR
In this article, the authors deal with the analysis of two essential parameters i.e. image resolution and field of view of both systems and demonstrate that the maximum spatial frequency that captured by the CCD depends on object size and pixel pitch of CCD camera when distance between object plane to hologram plane is kept constant.Abstract:
Space Bandwidth Product (SBP) is a process by which the imaging capacity of an optical is measured. The space bandwidth product analysis for inline and off-axis digital holography process is studied. This paper deals the analysis of two essential parameters i.e. image resolution and field of view of both systems. By this demonstration the maximum spatial frequency that captured by the CCD depends on object size and pixel pitch of CCD camera when distance between object plane to hologram plane is kept constant.read more

Reciprocal 360-deg 3D light-field image acquisition and display system [Invited]
TL;DR: A reciprocal 360-deg three-dimensional light-field image acquisition and display system was designed using a common catadioptric optical configuration and a lens array and showed quality measures such as angular resolution and space bandwidth product based on design parameters.

Wavefront Reconstruction with Diffused Illumination and Three-Dimensional Objects*
Emmett N. Leith,Juris Upatnieks +1 more
TL;DR: Three-dimensional holograms of transparencies produced in diffused light are of a quality comparable to pictures produced by conventional photography with incoherent light and have all the visual properties of the original scene.

Handbook of Holographic Interferometry: Optical and Digital Methods
TL;DR: In this paper, the Fourier Transform is used for the reconstruction of digital Holograms, and the convolutional approach is used to reconstruct the Holographic Histogram.

Space–bandwidth product of optical signals and systems
TL;DR: A quasi-geometrical representation of the space–bandwidth product in the Wigner domain is claimed to be more useful than a pure number that counts the degrees of freedom of the system.
