The invention of holography by Gabor was in many respects ahead of other work and ideas in the processing of images, and as such was unique.

G. Saxby [10] reports in his 1988 book that there were six and a half thousand papers on holography, of which he judged ‘….. more than a thousand … contain material of importance’.

His invention was many years before the invention of the laser (~1960) provided a source of sufficiently coherent light to make optical holography a practically useful and very significant technique.  However the 1947 invention itself led to a new understanding of signal processing of images, and to such ideas as the Gabor Transform and, with the Wigner Transform, was a basis for wavelets and other methods which are now widely used in digital signal processing.  Thus an important aspect of Gabor’s holography invention was the additional viewpoints that the concept brought to the field of signal processing, leading to many novel ideas.  Many of these ideas arose during his time at Imperial College.
