The properties of a pseudodeep hologram are studied. This new term refers here to an inclined thin hologram on which a one-dimensional line object is recorded by a sagittal system of beams. In this case the reconstructed image is read out only within the line corresponding to the object. It is shown that, similar to a deep 3-D hologram, the pseudodeep hologram has high angular and spectral selectivity. A simple graphic method for the construction of the images restored by the pseudodeep hologram ...

A new method of 3D image formation is proposed. A 3D image is generated in this case by a matrix of aspects of a 3D scene that are focused in spots. The matrix is formed by a laser scanning beam in which the aspects of the scene are introduced in consecutive order. As a result the observer sees on the screen a 2D image whose configuration changes depending on the position of the eye in such a way as if the observer examines the real 3D object. The optical scheme of AFS Display (Aspect-Focused-in- ...

A pseudodeep hologram is a thin, inclined hologram on which a one-dimensional line object is recorded by a sagittal beam system; at reconstruction, the object is read within the limits of the narrow line which corresponds to it. High angular and spectral selectivities have been obtained by these means. Attention is presently given to the possibility of recording and associative reading, in view of results from experiments in which the associative reading of a pseudodeep hologram was performed on ...

Selectogram characteristics are analyzed. The term selectogram stands for the structure obtained by recording the interference pattern of the radiation of an object and that of an extended reference source of light on an inclined photographic plate. Unlike a hologram, the selectogram reproduces 3-D images of objects by selecting definite components out of the radiation of an extended source whose phase distribution is not correlated with that of the reference source used at the recording stage. ...

A number of points concerning display holography and a method of so-called pseudo-deep holograms are reviewed. The possibility of using the angular selectivity property of pseudo-deep holograms for 3-D image formation is investigated. The optical system characterized by the presence of an inclined hologram and a horizontal slit that filters the beams from an object and those from an extended reference source is considered. It is shown that the hologram recorded with the help of such a system is ...

A method for 3-D image recording and reconstruction when using a so-called reference-free selectogram is suggested. According to this method, the light scattered by the object is filtered by a horizontal slit and then is split into two components with the help of a diffraction grating that is positioned just in front of a thick-layered photographic plate. The interference pattern that originates as a result of the interaction of the components formed by the diffraction grating is recorded in a lightsensitive ...

Results of experiments on synthesis of a thick-layered light-sensitive material on the base of gel-like dichromated gelatin are presented. In these experiments, the coated layer of liquid dichromated was not subjected to drying but it was sealed between two glasses in order to be protected from drying. The recording was performed on moisture-saturated layers after the liquid was transformed into gel. The thickness of the layer varied from 1 to 3 mm. The maximum efficiency of transmission holograms ...

Thick-layered self-developed glycerol-added dichromated gelatin has been suggested for the recording of volume holograms. The thickness of the layers varied from 0.4 to 0.6 mm. The diffraction efficiency is equal to 30% at the exposure about 5 J/cm 2 .

Here a method for data storage by means of multiplexing 3D holograms is considered. The method consists in shifting the recording material with respect to a reference speckle wave. The experimental data on the dependence of the diffraction efficiency of the hologram with respect to the shift is presented. The general scheme of data storage in 3D-speckle shift hologram is considered and presented. It's shown that this kind of hologram substantially outperforms all other types for the number of cells ( ...

Professor Jeong asked me to touch some personal moments of my scientific biography in my report. I am glad to do that. I started my way in display holography long ago, in 1958. The term "hologram" was known at that time to a dozen of specialists, and the term "display holography" has not existed at all.

A new method of wavefronts' cross-correlation by means of so-called Second-Harmonic-Generated Hologram (SHG hologram) is considered. According to this method the interference pattern of an object wave and a reference wave is recorded in nonlinear light-sensitive material using its second order nonlinearity. The SHG hologram generates the wave that forms the reconstructed image of the object without time delay in the moment when interfering wavefronts intersect the image of the object without time ...

The phenomenon of imaging properties of a material model of light intensity waves is analyzed in its various manifestation. (1) In the field of static intensity waves two types of records are considered: volume hologram and selectogram. Unlike the volume hologram, selectogram is not so sensitive to the degree of temporal coherence of recording light. (2) In the field of holographic recording of moving patterns of intensity waves several methods are considered. Doppler hologram presents the dynamic ...

Some new results of experimental study of multifrequency χ (2) -dynamic hologram image formation are presented. The main distinguishing feature of our experiments was the use not only of a multifrequency object wave but a multifrequency reference one, too. As a result, we have simultaneously observed at the same wavelength (λ=564 nm) two frequency summing holographic images formed by nonlinear crystal KTP and arranged nearly symmetrically around SHG image (λ=432 nm) both in transverse and longitudinal ...

Some properties of a pseudodeep hologram are considered as applied to the problems of optical computing. It is shown that the diffraction efficiency of this type of hologram can be increased by means of increasing the inclination factor of rays that intersect the light-sensitive layer.

The analysis of selectogram characteristics is carried out. The term selectogram stands for the structure obtained by recording the interference pattern of the radiation of an object and that of an extended reference source of light on an inclined photographic plate. The current presentation describes a case for which the image of the object being recorded is focused near the surface of the selectogram. It is shown that in this case the angular size of an element determining the resolving power ...

Two types of holographic 3D imaging systems are considered. The first one is based on a so-called selectrogram, i.e., the structure that can be registered by using the light scattered by the object as a reference one. The distance to the object is not limited in this case because it does not effect the capability of the light scattered by the object to interfere with itself. Two methods that permit us to increase the diffraction efficiency of the selectogram are discussed and investigated. The first ...

The expressions are deduced that determined the wavelength of the reconstructed wave and directions of propagation of the rays of light that form the image. An experiment is carried out on the base of a noncollinear scheme of nonlinear interaction. A hologram was recorded in a KTP crystal ...
