چکیده

Digital holography development has reached the level, which allows mass-manufacture of large size digital holograms – i-Lumograms, as well as manufacture of colour reflection holograms for security applications. Geola Digital also has proved that colour reflection holograms can be used as auto-stereoscopic projection displays for 3D gaming and home cinema applications. All that became possible by developing a full range of necessary holographic machinery that includes digital laserless life scenes imaging equipment, digital holographic printers and copying machines where our new copying method is implemented. Printing and copying machinery works with pulsed colour lasers. All Geola machinery exists as working laboratory equipment and is used by us for continuous printing of digital holograms. Image creation, hologram printing and copying processes can be completely separated geographically.

Applications of Holography in Fluid Mechanics and Particle Dynamics

The quantification of three-dimensional (3D) flow structures and particle dynamics is crucial for unveiling complex interactions in turbulent flows. This review summarizes recent advances in volumetric particle detection and 3D flow velocimetry involving holography. We introduce the fundamental principle of holography and discuss the debilitating depth-of-focus problem, along with methods that ...

Pulsed Full-Color Digital Holography with a Raman Shifter

Holography deals with processes involving the transformation of waves by interference structures that are formed when coherent electromagnetic waves interact with matter (Andreeva, 2002). As an optical technique it was introduced in the seminal works of Gabor, Leith, Denisyuk and others in the 1960’s (Benton, 2005). By succeeding to reconstruct the complete wave (full amplitude and phase inform...

Image Quality Improvement of Digital Holography by Multiple Wavelengths or Multiple Holograms

Digital holography (Yamaguchi & Zhang, 1997; Osten et al., 2002; Kreis, 2005; Ferraro et al., 2005; Frauel et al., 2006; Nomura & Imbe, 2010) is a useful technique for recording the fully complex field of a wavefront. In line with advances in imaging devices such as CCDs, digital holography is accessible. The digital holography has been used for lots of applications including encryption (Javidi...

حذف پراش مرتبه صفر در تصاویر بازسازی شده به روش تمام‌نگاری دیجیتالی

The numerically reconstructed images in digital holography contain two undesirable features. After reconstruction, the zero order diffraction as well as the complex conjugate image will be present in pictures and drastically reduce their qualities. Practical applications of digital holography in the context of characterization and measuring the physical properties of objects require the suppres...

Development of 3D measurement system using phase-shift digital holography

We propose a digital holography reconstruction method using convolution approach rather than the conventional Fresnel approach. Simultaneously, we propose a 3D measurement system of phase-shift digital holography using principle of light detector. Using proposal method, we develop a compact 3D measurement system of phase-shift digital holography with low price and high measurement accuracy. Key...
