A Study on the Case Analysis of Cultural Heritage Exhibitions using Hologram Technology

A hologram is described as a 'screenless display' that provides a realism and three-dimensional effect as if seeing a real object, and refers to a technology that implements a three-dimensional stereoscopic image using laser light. These holograms are currently being used in various cultural industries such as performances, exhibitions, and advertisements. In particular, pseudo-holograms such as floating techniques are mainly used in the cultural heritage exhibition field. However, pseudo-holograms can implement the same effect as holograms that show virtual 3D images in the real world, but there are still practical and technical limitations in satisfying audiences who want perfect 3D images like those seen in science fiction movies. The hologram, which is attracting attention as a future high-value-added imaging technology, can naturally reproduce real or virtual objects in a three-dimensional space as if they were real. In addition, holography technology is expected to lead the growth of the immersive content industry in the future by improving the technical limitations of the current augmented reality(AR) or virtual reality(VR). Therefore, if the current holography technology is gradually improved and supplemented with hologram screen, hologram printing, and plenoptic visualization technology, it is expected that the field of digital heritage contents and exhibitions using hologram will further develop in the future.
