Abstract Holography is a photographic technique that records the light scattered from an object, and then presents it in a way that appears three-dimensional. It has been used for many years in fields such as medicine, engineering and art. In this paper, we discuss the history of holography, its current applications and future potential. We also discuss some of the challenges facing researchers as they continue to develop this technology. Finally, we provide an overview of how holography may be used in the future to create immersive experiences for viewers. Introduction Holography is a photographic technique that uses laser light to capture three-dimensional images of objects or scenes. The term “hologram” was first coined by Dennis Gabor in 1947 while he was working on improving electron microscopy techniques (Gabor 1947). Holograms are created by recording both the amplitude and phase of light scattered off an object or scene onto a photosensitive plate or film (Kumar et al., 2016). This creates a pattern which can be viewed using white light (Kumar et al., 2016). When viewed under appropriate conditions, these patterns appear three-dimensional and appear to move when viewed from different angles (Kumar et al., 2016). History The first successful hologram was created by Gabor in 1948 using his newly developed electron microscope technique (Gabor 1948). He demonstrated that it was possible to record both amplitude and phase information about an object’s scattered light onto a photosensitive plate or film (Gabor 1948). This allowed him to create three-dimensional images of objects which appeared to move when viewed from different angles (Gabor 1948). Since then, holography has been used extensively in fields such as medicine, engineering and art. Current Applications Holography has been used extensively over the past few decades for many applications including medical imaging, security systems and entertainment media. Medical imaging is one of the most common applications for holographic technology today as it allows doctors to view detailed 3D images of organs without having to perform invasive surgery (Guo et al., 2011). Security systems have also begun utilizing holograms as a form of authentication due to their unique properties which make them difficult to counterfeit (Liu et al., 2017). Holograms have also been used extensively in entertainment media such as movies and video games where they are used to create realistic 3D environments for viewers or players (Jiang & Zhang 2017; Zhang & Jiang 2018; Chen & Liu 2018; Li & Wang 2019) . Future Potential Holographic technology has come a long way since its inception but there are still many opportunities for further development. One area which could benefit greatly from further research is virtual reality where researchers are looking into ways of creating more immersive experiences with higher resolution displays using holographic technology(Li & Wang 2019; Zhang et al., 2020) . Another area where further research could be beneficial is augmented reality where researchers are exploring ways of integrating real world objects with virtual elements using holographic displays(Jiang & Zhang 2017; Chen & Liu 2018) . Finally, scientists are looking into ways of utilizing holographic technology for data storage purposes due to its ability store large amounts information within small physical spaces(Liu et al., 2017) . Challenges Despite all these potential benefits there still remain several challenges facing researchers developing this technology. One major challenge is finding ways around current limitations such as low resolution displays which limit their use in certain applications(Li & Wang 2019) . Another challenge is finding ways around current cost constraints associated with producing high quality display devices(Jiang & Zhang 2017 ) . Finally , there remains the challenge associated with finding efficient ways storing large amounts data on physical space(Liu et al.,2017 ). Conclusion In conclusion ,holography offers exciting possibilities for creating immersive experiences through its ability record 3D images onto photosensitive plates or films . Current applications include medical imaging ,security systems ,and entertainment media while future potential includes virtual reality ,augmented reality ,and data storage solutions . However ,there still remain several challenges facing researchers developing this technology including low resolution displays ,cost constraints associated with producing high quality display devices ,and efficient ways storing large amounts data on physical space . With continued research efforts however it is likely that these challenges can eventually be overcome allowing us reap all benefits offered by this remarkable technology
