Described is a method for holographic reconstruction of diffusely illuminated objects which suppresses the known effect of granularity. The experimental setup is modest. It consists of a source of polychromatic light. Additionally there are inserted a simple ground glass and a diffraction grating in the reconstruction wave. Holographic reconstruction without granularity is achieved by incoherent superposition of longitudinal modes of the reconstruction wave.

A Journal of Physical Sciences: Zeitschrift für Naturforschung A (ZNA) is an international scientific journal which publishes original research papers from all areas of experimental and theoretical physics. In accordance with the name of the journal, which means “Journal for Natural Sciences”, manuscripts submitted to ZNA should have a tangible connection to actual physical phenomena.
