Hologram refers to an image that is created when the light reflects upon meeting an object. Hologram consist of two beams; a reference and an object beam which are diverted with the help of a half mirror and then the light converges forming a hologram using two full mirrors. 

According to Haleem, et al. (2020) there is a lot of potential for the use of holograms in the medical field in areas like training and education as well as advanced imagery for diagnosis and planning. 

The Earth Observing Laboratory uses holography to determine the size, shape and position of hydrometeors. These holograms are then processed and size distributions are produced.  The technology has sufficient resolution to determine the sizes and locations of cloud droplets as well as ice crystals.

Some holograms are complex and hard to create such as foil holograms in currency. With complex images and serial numbers imprinted or engraved underneath it makes it difficult to counterfeit. 

Holograms have the potential to change the way consumers interact and consume media across a number of entertainment applications. Whether it be paying tribute to artists of the past or accessing artists remotely,  holographic technology could extend the production and execution of live events to future-world scenarios previously limited to science fiction.
