Paper Abstract

With their introduction of diffused illumination Leith and Upatnieks introduced one the most essential inventions in holography and in modern optical engineering in general. They observed for the first time the enormous capability of utilizing the phase of a light field in a random-like manner for manipulating its characteristics when propagating in space. The use of phase freedom beyond lens-like manipulations in optical engineering was born. We like to place their invention into a broader context and discuss its enormous impact on most actual developments in optical engineering.
