On-line reconstruction of electron holograms

Proceedings, annual meeting, Electron Microscopy Society of America, 1993
Electron-off-axis holography has proven to be a most promising tool for the collection of the complete information about amplitude and phase modulation of the complex electron image wave in one single micrograph. Then amplitude and phase can be reconstructed numerically, offering almost any wave-optical possibility for the evaluation of the electron ...

SOUND HOLOGRAMS AND OPTICAL RECONSTRUCTION

Applied Physics Letters, 1966
A hologram has been made of an object illuminated by ultrasound, using the deformation of the water surface by radiation pressure. An optical reconstruction of this sound hologram with laser light has been achieved.

Method for reconstructing a hologram using a compact device

Applied Optics, 1992
A compact method for reconstructing a hologram is proposed in which the visible laser diode is used as a light source and the diffractive element is used to generate a collimated beam. The dependence of diffraction efficiency on the polarization of the beam is analyzed and the experiments with hologram reconstruction are reported.

Reconstruction of Transmission Holograms in Reflection

Optica Acta: International Journal of Optics, 1974
It is shown that an object wave can be reconstructed from a hologram by reflecting the illuminating wave from it. The image thus formed arises due to the backward coherent scattering from the metallic silver particles in the emulsion.

Hologram reconstruction by use of optical wavelet transform

Applied Optics, 1999
High-speed in-line holography is used to visualize the trajectories of glass fibers being drawn out in a turbulent flame. To improve the signal-to-noise ratio, the images are not observed by a conventional reconstruction setup, but the holographic plate is placed directly on the input plane of a wavelet-transform optical system.

Reflection hologram for reconstructing deep images:?errata

Optics Letters, 1998
On p. 1725 of Ref. 1, in the 20th line in the righthand column, the printed phrase "two-step time diffraction" should read as "two-step diffraction."

Moiré analysis of the reconstruction accuracy and uniformity of holograms

Optics Letters, 1986
A moiré technique for the analysis of the reconstruction accuracy and uniformity of holograms is presented. A Ronchi ruling is recorded holographically, and the image is cast on the object ruling. The superposition of the two rulings forms a moiré pattern that serves for the evaluation of the holograms.

Reconstruction dynamics of recorded holograms in photochromic glass

Applied Optics, 2011
We have investigated the dynamics of the record-erase process of holograms in photochromic glass using continuum Nd:YVO₄ laser radiation (λ=532 nm). A bidimensional microgrid pattern was formed and visualized in photochromic glass, and its diffraction efficiency decay versus time (during reconstruction step) gave us information (D, Δn) about the ...

Inverse problem approaches for digital hologram reconstruction

SPIE Proceedings, 2011
Digital holography (DH) is being increasingly used for its time-resolved three-dimensional (3-D) imaging capabilities. A 3-D volume can be numerically reconstructed from a single 2-D hologram. Applications of DH range from experimental mechanics, biology, and fluid dynamics.

Reconstruction of Inhomogeneous Scattering Objects from Holograms

Applied Optics, 1974
An experiment is reported in which the one-dimensional scattering potential along a line through a semitransparent bar with nonuniform index of refraction is determined from holographic measurements of scattered monochromatic light waves. The experiment is performed using an inhomogeneous bar for the first time in order to test quantitatively a ...
