“…It can be categorized into a few types such as HS printing, holographic fringe printing, and wavefront printing. Also, there are several researchers have proposed valuable research for holographic stereogram (HS) printing [3][4][5][6][7][8][9][10]. In addition, a digital holographic printing that records a color image hologram with a full parallax of 120° is presented [11].…”

In this paper, simplified digital content generation using single-shot depth estimation for full-color holographic printing system is proposed. Firstly, digital content generation is analyzed completely before the hardware system of holographic printing is run to provide a high-quality three-dimensional (3D) scene without degrading information of the original 3D object. Here, the single-shot depth estimation method is applied, and 3D information is acquired from the estimated highquality depth data and a given single 2D image. Then the array of sub-holograms (hogels) is generated directly by implementing fully analyzed computation considering chromatic aberration for full-color printing. Finally, the generated hogels are recorded into holographic material sequentially via effectual time-controlled exposure under synchronized control with three electrical shutters for RGB laser beam illuminations to obtain full-color 3D reconstruction. Numerical simulation and optical reconstructions are implemented successfully.

“…Moreover, there are several articles for full-color holographic printing and those are especially focused on wavefront printing.

In this paper, color optimization of a full-color holographic stereogram printing system using a single SLM based on iterative exposure is proposed. First, an array of sub-holograms (hogels) is generated effectively within fast computergenerated integral imaging, and fully analyzed phase-modulation for red, green, and blue (RGB) channels of hogel. Then, the generated hogels are recorded into holographic material sequentially where SLM displays the R, G, and B channels of a single hogel via effectual exposure under synchronized control with three electrical shutters for RGB laser illumination to obtain verified color optimization. Numerical simulation and optical reconstructions are implemented.

“…Once the CGH is projected onto the SLM, it is necessary to use optical setups to transmit the diffracted wavefront to the recording plane. Various optical setups of wavefront printers have been developed and reported in the literature for recording [5,6,[9][10][11][12][13][14][15]. These optical setups play an important role in recording of holograms and performance of a printer.…”

Holography enables 3D visualization of scattered optical fields recorded from three dimensional (3D) objects. This has led to dedicated research efforts towards developments of holographic displays utilizing holographic imaging techniques. The fundamental drawback of holography is that real objects must be used to capture holograms, despite the fact that it is a generic approach for reconstructing 3D information. One of the most promising technologies for addressing this issue is holographic printing which is also able to synthesize combined real 3D and virtual objects. These printers are capable of producing holograms that can replicate all physiological depth signals of actual objects. Reconstructed images are therefore exceedingly realistic and avoid the accommodation-convergence dilemma that other 3-D display methods, such as stereoscopic displays have. Inside a light-sensitive material, reference and signal beams are utilized to create interference, but the recording is local and the procedure is a point-to-point recording of the overall interference pattern. Researchers have contributed in development of different optical schemes for holographic wavefront printers. In this study, we examine the different optical schemes that are adopted for development of holographic wavefront printer and compare their performance. The impact of different optical configurations on the quality of reconstructed images is analyzed in optical design simulation platform and experimental researches. In order to evaluate the performance of a particular set-up, we determine the structure similarity index measure (SSIM), viewing angle of reconstructed image, and diffraction efficiency of the recorded hologram. Experimental and simulated findings are studied and presented.
