摘　　要：The invention of Holography by Dennis Gabor1 goes back to the year 1948.Gabor could show that the complete original wavefront of the object both with its amplitude and phase can be reconstructed by adding a coherent background to a wave coming from an object while recording in a storage medium.However,because no adequate source of coherent light was available at this time,the small coherence length of the mercury lamp forced him to arrange everything along one axis.This setup,known as in-line holography,has the disadvantage that the desired reconstruction is in line with disturbing diffraction orders,and can be separated from these disturbances only by focusing.Gabor finally gave up his investigations and mentioned in 1955 to his collaborator Michael W.Haine,“It was a very ill wind which I let out now almost eight years ago which blew nobody any good,least of all to myself.”
