For 60 years, high-energy pulsed lasers have enabled the recording of extremely realistic portraits of living people within a few nanoseconds. In the 21st century, this confidential technique, which requires great skill and equipment, has almost disappeared because of the final monochromatic color of the holograms, which does not appeal to the public. In this study, we show that ultra-realistic, full-color, and full-parallax snapshot holographic portraits can be recorded using a limited number of synchronized HD cameras. Experiments were successfully conducted using the digital CHIMERA holographic stereogram printing technique combined with image interpolation using a neural network. This new recording method allows holographic portraits to be developed and disseminated to the public on a larger scale.

Architects, engineers, and designers normally visualize architectural, urban planning, urban design, or landscape design projects in different ways to present their ideas. At present, the two most widely utilized and accessible methods for spatial visualization are digital 3D modeling and physical 3D modeling. Despite their popularity, both approaches have intrinsic limitations. These shortcomings are progressively being mitigated through advancements in technology and digitalization. In this study, we propose the utilization of hologram technology as an innovative approach to overcome the limitations of both modeling methods mentioned. This research addresses two main points: the seamless integration of hologram production into the standard workflow of architectural and urban design projects, and the experimental creation of a tabletop hologram prototype using the most advanced stereoscopic visualization capabilities—CHIMERA hologram printer. The experiment’s results indicate that tabletop holograms’ visualization quality can potentially replace traditional methods in the near future. The process of creating holograms can be incorporated into the standard workflow of architectural and urban design projects and utilized in specific contexts.

Digital holographic stereograms have met expectations in various fields since their introduction. Traditionally, recording large outdoor physical models has required time-consuming and complex processes involving professional tools and technical expertise. This study, however, aims to streamline the process by utilizing simple equipment, such as an iPhone, basic tools, free phone applications, and free software. Four successful experiments were conducted and evaluated using the digital CHIMERA holographic stereogram-printing technique combined with photogrammetry, Gaussian splatting, light detection and ranging (LiDAR), and image interpolation. This approach records large-scale outdoor content more efficiently and effectively. The selected method allows the development and large-scale dissemination of realistic outdoor content holograms to the public. This study demonstrates the feasibility of creating ultra-realistic outdoor holograms using accessible tools and methods, offering potential applications in various fields such as art, education, and entertainment.

This study simplified the creation of holographic stereograms using AI-generated prompts, overcoming the conventional need for complex equipment and professional software. AI enabled the generation of detailed perspective images suitable for various content styles. The generated images were interpolated, upscaled, and printed using a CHIMERA holoprinter to obtain high-quality holograms. This method significantly reduces the required time and expertise, thereby making holographic content creation accessible. This approach demonstrated that AI can effectively streamline the production of high-fidelity holograms, suggesting exciting future advancements in holographic technology.

The evolution of cartography poses challenges in representing three-dimensional terrain accurately on traditional two-dimensional maps. Providing an accurate 3D view of the area, coupled with essential geographic information, is vital for rapid and accurate decision-making in emergency management and response. Holography offers a promising solution by providing immersive three-dimensional visualizations. The field of hologram mapping, although novel, is still developing. Given its nascent stage, several limitations are evident. This study addresses one such limitation—inaccuracies in distance measurement—by presenting a hologram map that integrates two-dimensional and three-dimensional information. Accurate distance information on maps is critical for operational success. We aimed to improve hologram maps by integrating contour lines. Our approach allows users to measure distances from near-perpendicular angles while viewing 3D features from other perspectives. We review current advancements in hologram mapping, highlight existing limitations, and introduce our innovative solution designed to enhance both accuracy and usability. Our experiment resulted in a hologram map that accurately depicts a 3D environment, integrates contour lines, and allows for distance and slope angle measurements. The hologram map fills the research gap by providing accurate 3D visualization and distance measurement, signifying a major advancement in hologram mapping.

In the history, architects, engineers or artists traditionally visualized architectural, urban planning, urban design, or landscape design projects with physical models in a smaller scale to represent their ideas. The biggest problems of traditional materialistic models are the long production time and limitation of mobility. Thanks to advancements in digital technology, 3D models can now be generated easily from 2D blueprints using computer software. However, eventually the digitalized approach could not replace the whole industry of making physical models, because of a lack of stereoscopic 3D imaging of space and structures. In this study, we discuss two points: the normal procedure of visualizing 3D models in urbanism and architecture design projects; and proposal of the stereographic hologram visualization for 3D models created with CHIMERA hologram printer as a new approach to solve all the problems in spatial projects visualization of both digitalized and physical models. The experiment's results indicate that tabletop holograms' visualization quality can potentially replace traditional methods in the near future. Moreover, the input data for this method can be seamlessly integrated into current architectural and urban design workflows, making holograms a promising approach for 3D immersive content in this field.
