The invention relates to a holographic display comprising a lighting device, a magnifying unit (VE) and a light modulator (SLM), wherein the lighting device comprises at least one light source and a collimation unit (LCU), wherein the collimation unit (LCU) is designed such that it collimates the light of the at least one light source and generates a light wave field of the light of the light source with a predeterminable plane wave spectrum, wherein the magnifying unit (VE) is arranged downstream of the collimation unit (LCU) in the light propagation direction, wherein the magnifying unit (VE) comprises a transmissive volume hologram (VH) that is arranged and designed such that, on the basis of a transmissive interaction of the light wave field with the volume hologram (VH), an anamorphic divergence of the light wave field can be achieved, and wherein the light modulator (SLM) is arranged in the light propagation direction either upstream or downstream of the anamorphic magnifying unit (VE). |
