Abstract
In presented paper we study the influence of spatial and temporal coherence of light source on resolution and depth of focus of holographic reconstructions. Presented holographic display setup uses phase - only spatial light modulator and realizes complex coding shame which allows to reconstruct objects in volume centered around plane of the modulator. In simulations we implement partially coherent reconstructions of complex hologram theory. It allows to investigate quality of holographic reconstructions for various degree of illuminating light coherence. During experimental tests we validate simulation results. We show that the influence of spatial coherence effect of light source on resolution of reconstructed objects is stronger than that of temporal coherence. Moreover we prove that it is possible to obtain high quality holographic reconstructions for large size source and wide spectrum for objects having large depths.
