Abstract

Diffusers play an important role in optical and digital holography, because they can improve the quality of the reconstructions. However, the application of diffusers generally suffers from a severe drawback: they introduce a speckle pattern which may disturb the reconstruction. An analysis of the speckle phenomenon reveals the possibility to avoid speckle by the use of special diffusers which can be designed by digital techniques.
