History of hologram

A hologram is created by capturing the light reflect from an object and reconstruct it so the subject appears to move relation to the position of the watcher of the hologram. This is what makes a hologram appear 3-dimensional but in fact it is not, it is a 2-dimensional symbol just as an normal photograph.

In 1947, Hungarian physicist, Gabor Denes (known as Dennis Gabor in English) was playing in his lab with the consequences of ground-breaking technological advances dealing with the development of the electron microscope. Dennis Gabor was awarded the Nobel Prize for Physics for his discovery but he had to wait until 1971 to receive the recognition he deserved.

The discovery was complete in England at the profitable lab of British Thomas-Houston who filed a patent back in 1947, however the holographic light/optical technique did not attain any commercial significance until the development of the in 1960. With the invention of the laser, 3-dimensional objects were then able to be made and the technique was first discovered in 1962 by two sets of teams - one in Soviet Russia led by Yuri Denisyuk and in the US, led by Juris Upatnieks.
