Optical holography is an excellent technology which can be applied in many fields, such as 3D-displays, information storage, products packaging, interferometer survey, optical connection and computer and so on. The conventional holography include reference wave, object wave and diffracting wave. These optical waves are spatial light and the whole hologram set up is fair size. The optical wavegu...

An expression derived for hologram exposures made along the straight-line portion of an H-D curve of a photographic plate gives the first-order transmittance of a hologram made of several object points exposed simultaneously (conventional holograms). This expression is compared with a similar expression derived previously for holograms made of several object points exposed sequentially (synthet...

Here we present an approach for creating full-color digital rainbow holograms based on mixing three basic colors. Much like in a color TV with three luminescent points per single screen pixel, each color pixel of initial image is presented by three (R, G, B) distinct diffractive gratings in a hologram structure. Change of either duty cycle or area of the gratings are used to provide proper R, G...

The enhanced-NA Fresnel hologram reconstructs a holographic image at viewing angle larger than the diffraction of pixel. space is limited by bandwidth digital hologram. In this study, we investigate property formation in extended beyond zone. A numerical simulation, using phase hologram, carried out to observe an extension and effect on changes angular field view. synthesized restricting view r...

The techniques of small particle holography are extended in an elementary way to show that multiple exposure holography can be used to study the dynamic properties of particle fields. Experimental techniques for performing such a study are then described. Finally, as a typical example, a multiple exposure hologram of an aerosol is presented with a portion of the data extracted from it. The holo...

This paper presents a method for reducing noise in a digital hologram, which occurs during acquisition. The algorithm proposed initially transforms a digital hologram into frequency-domain data through a discrete cosine transform (DCT), and separates the object from the background in the transformed image. As a noise reduction method, a histogram modification method is applied to the object, wh...

In this paper we present an approach for the holographic imaging of objects composed of splines. It is based on an imaging method for lines and extended to fit the requirements for the visualization of 3D curves. The input object consisting of splines is decomposed into line segments. These segments are subsequently transferred into the holographic equivalent—a set of textured rectangles approp...
