Abstract
Holographic light shaping has a myriad of applications. But the occurrence of coherent artifacts (speckle) hampers its use for the reconstruction of continuous laser intensity profiles, such as images. Therefore, the reduction of speckle in holographically reconstructed images is a very active research topic, and a vast number of approaches are currently investigated. In this work, several speckle reduction methods based on intensity averaging and iterative algorithms were implemented. Sim-ulations and experimental results were obtained and compared against regarding perceived image quality, speckle contrast and reconstruction speed. The results show that the investigated methods allow the reconstruction of precise and high quality images
