, 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
Granular synthesis
Granular synthesis is a basic sound synthesis method that operates on the microsound time scale.It is based on the same principle as sampling. However, the samples are not played back conventionally, but are instead split into small pieces of around 1 to 50ms. These small pieces are called grains...
