Off-axis digital hologram reconstruction: some practical considerations. [PDF]

open access: yesApplied Optics, 2011
Holographic rendering of off-axis intensity digital holograms is discussed. A review of some of the main numerical processing methods, based either on the Fourier transform interpretation of the propagation integral or on its linear system counterpart ...

MODELLING AND RECONSTRUCTION OF GABOR-TYPE HOLOGRAMS

open access: yesDyna, 2011
Los procesos de modelación y reconstrucción de hologramas se soportan en el cálculo de la integral de difracción en su formulación de kirchhoff-fresnel o rayleight-sommerfeld. Dicha integral puede ser evaluada numéricamente por medio de diferentes formalismos: teorema de convolución, espectro angular y transformada de fresnel, entre otras.

When holography meets coherent diffraction imaging [PDF]

open access: yes, 2012
Modern imaging techniques at the molecular scale rely on utilizing novel coherent light sources like X-ray free electron lasers for the ultimate goal of visualizing such objects as individual biomolecules rather than crystals. Here, unlike in the case of

Solution to the twin image problem in holography [PDF]

open access: yes, 2006
While the invention of holography by Dennis Gabor truly constitutes an ingenious concept, it has ever since been troubled by the so called twin image problem limiting the information that can be obtained from a holographic record. Due to symmetry reasons

Maskless imaging of dense samples using pixel super-resolution based multi-height lensfree on-chip microscopy. [PDF]

open access: yes, 2012
Lensfree in-line holographic microscopy offers sub-micron resolution over a large field-of-view (e.g., ~24 mm2) with a cost-effective and compact design suitable for field use. However, it is limited to relatively low-density samples.

Dual wavelength digital holography for 3D particle image velocimetry [PDF]

open access: yesJournal of the European Optical Society-Rapid Publications, 2015
A multi-exposure digital in-line hologram of a moving particle field is recorded by two different wavelengths and at different times. As a result, during the reconstruction step, each hologram can be independently and accurately reconstructed for each ...

XUV digital in-line holography using high-order harmonics

open access: yes, 2007
A step towards a successful implementation of timeresolved digital in-line holography with extreme ultraviolet radiation is presented. Ultrashort XUV pulses are produced as high-order harmonics of a femtosecond laser and a Schwarzschild objective is used
