An updated diorama with a full-color H2 analog hologram

摘要

This paper presents an update of the traditional museographic diorama, with the addition of a full-color H2 analog hologram. It explains how it works, and indicates the benefits for museums. Unlike the Denisyuk color technique where the final image appears completely behind the surface of the hologram, the H2 hologram is a transplane image. To realize this new kind of diorama, an ultra-realistic "transplane" color hologram is recorded with the Ultimate holographic material and blends into a real three-dimensional scene where the viewer no longer knows where the real ends and where the virtual begins. The play of the hologram's lighting makes possible the objects appear or disappear in the decors and interact with the public. The result boosts the little outdated traditional diorama and meets the expectations of a modern audience interested in mixed reality.
