A holographic reconstruction system and a corresponding holographic reconstruction method are disclosed. The holographic reconstruction system comprises light source means for providing substantially coherent light, reconstruction means for holographically reconstructing a scene and for producing a visibility region from where the viewer can view the holographically reconstructed scene, and deflection means for positioning the visibility region. The aim of the invention is to improve the visibility region of a holographic reconstruction system. To achieve this aim, the holographic reconstruction system comprises deflection drive means for continuously rotating or pivoting the deflection means about a rotational axis at a rotary frequency, thereby displacing the visibility region. The invention allows one or more viewers to view the scene reconstructed by means of the holographic reconstruction system from different positions while facilitating the implementation of the holographic reconstruction system with conventional means.
