Holography is primarily at home in the fields of virtual and augmented reality, as well as industry and Industry 4.0. It describes a process for creating three-dimensional images - so-called holograms. Unlike a normal photograph, a hologram appears three-dimensional; you can view the image from different angles as if it were actually there. The technology behind it uses laser light, which strikes a special film, thereby creating a complete 3D representation.
In industry, holography is used for quality control, for example. Products can be checked with holograms to make even the smallest material defects visible. In virtual reality, holography enables impressive experiences: at trade fairs, for instance, visitors can see new machines „live“ in the room using holograms and operate them virtually, without the actual devices being on-site at all.
Holography is also known from security features, such as on banknotes or identity cards – the iridescent hologram helps to detect counterfeits. To summarise: holography opens up many new possibilities for making things vivid, secure, and experienceable from different perspectives.
