Brief History of Hologram | By Octagon Studio
In the words of one of the oldest and most acknowledged collegiate institutions throughout the world, Oxford University, hologram refers to special types of pictures in which the object is seemingly three-dimensional. This could happen when the light is reflected into certain patterns forming reflection of an object in form of transparent, intangible yet identical image. In today’s technology, hologram can be produced in various sophisticated ways and utilized for varied purposes as well. One of the most recognized use of hologram is bringing back the late artist Michael Jackson to the stage by projecting his recorded past performance into a modern, real time three-dimensional projection. Here is a brief history of hologram and its significant marks and figures.

The furthest track we can trail concerning the invention of the term hologram is Pepper’s Ghost concept back in the 19th century. It is a concept intended to perceive one’s perspective to see ‘ghostly’ images appear to fade in or out in a single media set to be used in a theater performance. In modest words, the audience could see intangible images floating on the stage as a depiction of ghost or alien. The term is named after its the technique’s inventor, John Henry Pepper who is among important names behind the story of hologram. After this, the important figures behind the history of hologram tend to be dominated by physicists.
The history of hologram reached its clearer phase where the term ‘hologram’ is coined. In 1947, Dennis Gabor came up with the words hologram which was derived from two Greek words which are Holos and Grammas. Holos means whole, while grammas signifies messages. Gabor was a Physicist working on X-ray microscopy in the 1940’s. Through his work along with his colleagues, he was granted the Nobel Prize in Physics. In about two decades after X-ray microscopy, Nicolay Bassov, Alexander Prokhorov, and Charles Towns were named the same award in same field for inventing laser. Laser become important for the development of hologram since it possesses pure and intense light making hologram more vivid.

The development of hologram technology reached its peak in 1970’. It was Llyod Cross who made hologram as we know it today. He worked on moving three-dimensional images by integrating cinematography with white-light transmission enabling us to see Michael Jackson perform after his unfortunate death years after. The history of hologram and its development involves extraordinary people with extensive studies and works making this technology one of the most exciting products of civilization. Therefore, the utilization is quite out of reach for daily use since it requires proper resources and studies which is inevitably pricey.
