Holograms are three-dimensional images created using the technique of holography. Unlike traditional two-dimensional images, holograms give the illusion of depth. This tricks viewers to perceive them as if they were real life objects in three-dimensional space. Holography is based on the principle of interference of light waves.
Microsoft describes Holograms for their Mixed reality headset the HoloLens as “objects made of light and sound that appear in the world around you like real objects.” Holograms within the headset will respond to your gaze, gestures, and voice commands. Whether you move around or move the holograms around they can interact with real-world surfaces around you. They are “digital objects that are part of your world.”
Holograms have various applications, including art, entertainment, scientific research, security, and data storage. They provide an immersive display that changes the way we live. We can now visuals things and have realistic three-dimensional representations that feel like they are in real life.
When were holograms created?
The development of holography and the creation of the first holograms is by Dennis Gabor, a Hungarian-British physicist. Gabor introduced the theory of holography in 1947, for which he was awarded the Nobel Prize in Physics in 1971.
However, it is important to point out that the first practical holograms were not created until the 1960s. These holograms could reproduce three-dimensional images. The advancement was aided by the invention of the laser, which provided a reliable and coherent light source necessary for holography.
In 1962, Yuri Denisyuk, a Soviet physicist, demonstrated the first true-color reflection hologram. This was another significant milestone in holography. After this breakthrough, holography continued to advance and through the late 1960s and early 1970s, holograms were being produced commercially and gaining attention as a unique visual medium.
Since then, holography has evolved further, with advancements in recording materials, laser technology, and digital processing techniques. Today, holography finds applications in a variety of fields, including art, entertainment, scientific research, security, and more.
