“…Production of stable reproducible hard-copies by a holographic printing, based on recording of volume holograms, requires reliable medium for permanent multicolor (RGB) holographic recording with high diffraction efficiency, sensitivity, resolution and signal-to-noise ratio across the visible region. The dichromate gelatin, photopolymers and silver halide provide parameters close to the requirements [55]. The non-satisfactory spectral response and low sensitivity of the dichromate gelatin exclude it from the list of candidates despite its low losses and high diffraction efficiency.…”

“…The silver halide emulsions are discrete carriers media in which recording occurs in nano-sized particles dispersed in a carrying gelatin matrix. They can boast with high sensitivity in a broad spectral range, diffraction efficiency of 80-98%, high resolution and dynamic range as well as long-term storage [55]. The drawback of the silver-halide emulsions is the low signal to noise ratio in the blue spectral region due to the light scattering.…”

“…Thus the 2D real-valued hologram (1) or (2) contains information about the phase of the light wavefront coming from the 3D object as a 2D fringe pattern. The most widely used for cultural heritage dissemination is recording of volumetype reflection holograms because they provide high-quality object reconstruction which could be observed in a wide viewing angle under illumination with a point source of white light [2,4]. Figure 1 shows two such holograms recorded in IOMT-BAS with a DPSS laser at 532 nm wavelength onto a silver-halide holographic plate.…”

Holography enables capture and reconstruction of the optical field scattered from three-dimensional (3D) objects. The hologram encodes both amplitude and phase of the field under coherent illumination, whereas photography records only the amplitude by incoherent light. 3D visualization feature of holography motivates expansion of research efforts dedicated to digital holographic imaging methods as a holographic display or a holographic printer. The paper presents two holographic 3D printing techniques which combine digital 3D representation of an object with analog holographic recording. Generation of digital contents is considered for a holographic stereogram printer and a recently proposed wavefront printer. These imaging methods could be applied to specific artifacts which are difficult to be recorded by conventional analog holography.

The intrinsic properties of holograms make 3D holographic imaging the best candidate for a 3D display. The holographic display is an autostereoscopic display which provides highly realistic images with unique perspective for an arbitrary number of viewers, motion parallax both vertically and horizontally, and focusing at different depths. The 3D content generation for this display is carried out by means of digital holography. Digital holography implements the classic holographic principle as a two-step process of wavefront capture in the form of a 2D interference pattern and wavefront reconstruction by applying numerically or optically a reference wave. The chapter follows the two main tendencies in forming the 3D holographic content-direct feeding of optically recorded digital holograms to a holographic display and computer generation of interference fringes from directional, depth and colour information about the 3D objects. The focus is set on important issues that comprise encoding of 3D information for holographic imaging starting from conversion of optically captured holographic data to the display data format, going through different approaches for forming the content for computer generation of holograms from coherently or incoherently captured 3D data and finishing with methods for the accelerated computing of these holograms.
