Dennis Gabor 110th birthday: Google is celebrating 110th birthday of holograph inventor engineer Dennis Gabor.Dennis Gabor he is actually a physicist who was born in the year 1900 ago today. Dennis Gabor was an electrical engineer and enventor who was the first to invent holography. Dennis Gabor was also awarded with the Nobel Prize in Physics.Google Doodle celebrating dennis gabor’s 110th birthday today on 5th june, 2010. As a Jew, Gabor fled from Nazi Germany in 1933, and was invited to Britain to work at the development department of the British Thomson-Houston company in Rugby, Warwickshire. During his time in Rugby, he met Marjorie Butler, and they married in 1936. He became a British citizen in 1946,and it was while working at British Thomson-Houston that he invented holography, in 1947.
He experimented with a heavily filtered mercury arc light source.
However, the earliest hologram was only realized in 1964 following the 1960 invention of the laser, the first coherent light source. After this, holography became commercially available.
Gabor’s research focused on electron inputs and outputs, which led him to the invention of re-holography.
The basic idea was that for perfect optical imaging, the total of all the information has to be used; not only the amplitude, as in usual optical imaging, but also the phase. In this manner a complete holo-spatial picture can be obtained.Gabor published his theories of re-holography in a series of papers between 1946 and 1951.
Gabor also researched how human beings communicate and hear; the result of his investigations was the theory of granular synthesis, although Greek composer Iannis Xenakis claimed that he was actually the first inventor of this synthesis technique.
