Abstract

A technique to reduce holographic-recording noise is described. The technique is based on encoding the object wave field with a finely structured, phase-changing screen, and subsequently retrieving the desired-image wave field by passing the reconstructed wave field through an identical, or closely matched screen. The object-shape-dependent noise, which is generated in the recording process, can be reduced by this technique. As an example, experimental results are presented showing noise suppression to approximately 3%.
