“…Holographic video displays have existed for Though the rapidly growing amount of 3D imagery means that there will likely be more use of holographic prints in the luxury goods world in the near future, the ultimate goal remains a dynamic holographic display. Holographic video displays have existed for many years, and like holographic prints, they do not require scene capture with coherent light sources but rather can create diffraction patterns from 3D models or parallax image sets [37]. Because of the requirement for submicron-scale pixels in the display device, inexpensively scaling up the necessary electro-optic components (in particular, diffractive spatial light modulators) to the sizes of the still hologram and Pepper's Ghost examples described above continues to be a topic for research and development.…”

The luxury goods industry and holography have a lengthy history together. In this article, we review the applications of holography to the industry and the relevant technical requirements, in particular when the hologram itself is the luxury item, when the hologram is used to promote luxury items, and when the hologram is used for authentication of luxury items. We then explore some possible scenarios for the evolution of this relationship.

“…To obtain a dynamic holographic 3D display, several approaches are possible: either using an electronically controlled phase modulator (such as a liquid crystal or acousto-optic modulator) [ 17 , 18 , 19 , 20 ], or using a refreshable holographic recording material, such as photorefractive polymer. The present review article focuses on this latter case, specifically the development of photorefractive materials and their use for holographic 3D display.…”

Photorefractive materials are capable of reversibly changing their index of refraction upon illumination. That property allows them to dynamically record holograms, which is a key function for developing an updateable holographic 3D display. The transition from inorganic photorefractive crystals to organic polymers meant that large display screens could be made. However, one essential figure of merit that needed to be worked out first was the sensitivity of the material that enables to record bright images in a short amount of time. In this review article, we describe how polymer engineering was able to overcome the problem of the material sensitivity. We highlight the importance of understanding the energy levels of the different species in order to optimize the efficiency and recording speed. We then discuss different photorefractive compounds and the reason for their particular figures of merit. Finally, we consider the technical choices taken to obtain an updateable 3D display using photorefractive polymer. By leveraging the unique properties of this holographic recording material, full color holograms were demonstrated, as well as refreshing rate of 100 hogels/second.
