Who Really Invented the Hologram?

Who Invented Hologram?

Hologram is a technological marvel that has amazed the world with a seemingly impossible optical illusion of three-dimensional objects. It has generated incredible synthetic realities in films, video games, and virtual reality. But have you ever wondered who invented this incredible innovation? In this article, we are going to explore the history and people behind the discovery of hologram.

The Concept of Holography

The concept of holography is rooted in the research and understanding of light and interference, which dates back to the 19th century. In 1817, a physicist named Augustin-Jean Fresnel introduced the wave theory of light, which states that light behaves as a wave, similar to water waves. In the following decades, scientists continued to study and build on Fresnel's theory, discovering that when two or more waves meet, they create a pattern of interference.

It wasn't until the 1940s when the idea of using interference for creating a three-dimensional image was proposed by the Hungarian-British physicist, Dennis Gabor. The concept was based on the principle that when light from a single source is split and reflected off an object, the resulting wave pattern can be recorded and transferred to another location. This idea led to the invention of holograms.

Dennis Gabor

Dennis Gabor was born in Budapest, Hungary, in 1900 and grew up during a time of great innovation and creativity in science. He studied electrical engineering at the Technical University of Budapest and later earned a Ph.D. in physics from the Berlin Institute of Technology. In 1948, while working for the British Thomson-Houston Company, Gabor invented the holographic method and published his research in Nature, a scientific journal.

Gabor's invention was revolutionary in the field of optics and visual communication. He received the Nobel Prize in Physics in 1971 for his work on holography and other inventions in the field of electron optics. Gabor's research and inventions have paved the way for modern-day technologies such as CD players, barcodes, and laser printers.

The First Hologram

The first experiment and public demonstration of the holographic method were performed by Gabor in 1948. He used a mercury vapor lamp to produce a coherent beam of light and a piece of glass covered with a thin layer of emulsion to record the interference pattern. The resulting hologram showed a three-dimensional image of a toy train and illustrated the potential of this technology for future applications.

Since Gabor's initial discovery, holography has progressed significantly, and today, it is utilized in a wide range of industries such as art, security, and medicine. Holograms are now used to produce credit cards, passports, and ID cards to prevent counterfeiting. They have also found their way into popular culture through movies, music videos, and live performances.


In conclusion, Dennis Gabor, the Hungarian-British physicist, invented the holographic method in 1948, which laid the foundation for the development of modern holography. Since then, this fascinating technology has allowed us to create realistic three-dimensional images that can fool our eyes in many ways.

While the concept of holography may seem complicated, it is based on simple principles of light and interference that have been studied for over a century. As we continue to explore and develop this technology, the possibilities for its application are endless, and we can expect to see more innovations in the future.

The Development and Popularization of Holograms

The concept of holograms had been around since the 1940s, but it was not until the invention of the laser in 1960 that holography became a viable technology. Although the first hologram was created by Denis Gabor in 1947, it was very dim and difficult to reproduce. It wasn't until the development of the laser that holography became a practical means of creating 3D visualizations.

Initially, holography was limited to scientific applications, especially in the fields of microscopy and interferometry. It wasn't until the 1970s that holography gained widespread popular appeal, largely due to the development of the rainbow hologram. Unlike previous holograms, which were monochromatic and required precise alignment to view properly, the rainbow hologram used white light to create a full-color, 3D image that could be viewed from any angle.

Further Developments in Holography

Since the 1970s, holography has continued to advance, with improvements made in hologram recording materials, hologram stability, and image resolution. Electronic holography, or "e-holography," has also emerged as a promising new field, where holograms can be created and viewed on digital devices. Another technological innovation, the use of holographic data storage, involves using lasers to store and retrieve massive amounts of data on a holographic medium.

One of the most significant advancements in holography was the invention of the digital holographic microscope (DHM), which allows for the creation of 3D images of biological specimens without the need for physically slicing the sample. The DHM is now used extensively in fields such as biology, medicine, and materials science for various research purposes.

Emmett Leith and Juris Upatnieks

The American engineers Emmett Leith and Juris Upatnieks are credited with making significant contributions to the development of holography. In 1962, they invented the technique that made it possible to create the first 3D hologram. The invention of the laser had made it possible to create a stable light source that could be split into two beams: the object beam, which would be reflected off an object to record its information, and the reference beam, which would interfere with the object beam to create the hologram.

The first hologram created using this technique was a simple toy train, which was later displayed at the Museum of Science and Industry in Chicago. Today, holography is used in a variety of fields, including security, entertainment, and scientific research.

Applications of Holograms

The vast array of applications for holograms is a testament to the versatility of this technology. In the field of art, holography is used to create stunning 3D images that captivate viewers. Holographic displays are used in entertainment, from concerts to theme parks, to add a new level of visual excitement to performances and attractions.

In the field of security, holograms are used to prevent counterfeiting and fraud. A hologram can be placed on a product or important document to verify its authenticity, as the print and texture of a hologram cannot be easily duplicated. Holograms are also used in scientific research, such as in holographic microscopy and interferometry, where they help scientists observe and measure phenomena at a microscopic level.

In conclusion, the origins of holography date back to the mid-20th century, but it was not until the invention of the laser that 3D holograms became a feasible reality. The field of holography continues to advance, with new developments in materials, electronic holography, and holographic storage. The contributions of Emmett Leith and Juris Upatnieks were instrumental in making holography more accessible, and today, the field is used extensively in research, art, entertainment, and security.
