Abstract

In this publication an experimental configuration for Digital Holography is presented which allows for a modification of the reference wave. Using a reflective liquid crystal Spatial Light Modulator (SLM) placed in the reference arm. The benefit of this approach is demonstrated by applying it to Digital Lensless Fourier Holography. As the optimal configuration of the reference wave depends on the position of the object under investigation, we use the approach to electronically adapt the reference wave to varying positions of the object along and perpendicular to the optical axis and without the requirement of mechanically moving parts.
