Holographic displays act as dynamic information displays to enrich our lives in terms of visual perception. In particular, holography forms a promising candidate for displaying three-dimensional (3D) scenes and objects without necessitating imaging optics. It provides glass-free, realistic, 3D displays, which satisfy each of the 3D requirements to impart stress-free natural 3D displays. Furthermore, additional 3D technologies such as light field and integral imaging are also promising candidates for next-generation displays. In any holographic display, significant research evaluating their visual perception is imperative for satisfactory functionality.
Displays are an essential component in almost every walk of life, and the increased access to digital technology has provided further drive for the development of highly functional displays; including 3D displays. Holography is of particular interest to both the public and researchers owing to its ability to generate realistic 3D displays. As such, a significant volume of research is being conducted worldwide with respect to their continued development. However, several breakthroughs are required ahead of the realization of large-format dynamic holography displays which update at video frame-rates. These limitations pose both technological and scientific challenges. Current digital 3D display technologies such as SLMs are small-scale, exhibit finite pixel size, and are costly. The generation and handling of computer generated holograms (CGHs) is another challenge owing to their size and there are, therefore, intrinsic difficulties in generating and processing these. Several hardware and software-based technologies have been developed in the hope of accelerating progress towards CGH generation. However, currently available recording materials do not support this technology and, as such, it is imperative to work collaboratively on developing technologies capable of handling the increased rates required for CGH generation.
Simultaneously, novel technologies which are expected to form the next generation of holographic displays are constantly emerging and the development of both their hardware and software, alongside the evaluation of their performance also poses a significant challenge.
