Fraunhofer diffraction patterns from apertures illuminated with nonparallel light in nonsymmetrical Fourier transformers

TL;DR: This work extends a 2-D axially nonsymmetrical Fourier transforming with an anamorphic system with the use of spherical illumination to obtain an exact Fourier transform and a greater angular magnification coefficient than with parallel illumination.

Simultaneously image and Fourier transform by circular zone plates: a simple method

TL;DR: On propose une methode simple pour obtenir simultanement et dans le meme plan l'image and the transformee de Fourier d'un objet avec seulement une onde d'eclairage utilisant les proprietes de diffraction des reseaux zones circulaires.
Book ChapterDOI

Elements of Holography and Image Modification

TL;DR: As was already pointed out in the introduction, holography has become such an extended field of optics that it is impossible to thoroughly treat the subject within such a limited space.

A study of generalized geometries for holography

T C Gupta, +1 more
- 01 Sep 1983 - 
TL;DR: In this article, a general analysis of various holographic geometries is presented, where the self-focusing action in the hologram is introduced and the expressions for image field intensities along with their coordinates and image field reconstructing conditions are derived.
Book ChapterDOI

Optical Linear Systems Under Coherent Illumination

TL;DR: In modern parlance, image science encompasses the basic principles and the engineering practice for acquiring, preprocessing, recording, and post-processing pictures.

Lensless Fourier-Transform Method for Optical Holography

TL;DR: Pastor and Arita as discussed by the authors used a gold-doped germanium detector with a straight xenon flash lamp in close proximity to the liquid nitrogen dewar containing the sample.
