Holography is particularly at home in the fields of virtual and augmented reality as well as Industry and Factory 4.0. It describes a process with which three-dimensional images - so-called holograms - can be created. In contrast to a normal photo, a hologram appears three-dimensional: you can view the image from different angles as if it were really there. The technology behind it uses laser light that hits a special film to create a holistic 3D image.
In industry, holography is used for quality control, for example. Products can be checked with holograms to visualise the smallest defects in the material. In virtual reality, holography enables impressive experiences: At trade fairs, for example, visitors can use holograms to see new machines "live" in the room and operate them virtually without the real devices even being on site.
Holography is also known from security features, for example on banknotes or ID cards - the shimmering hologram helps to recognise forgeries. To summarise: Holography opens up many new possibilities for making things clear, secure and tangible from different perspectives.
