The single projector is configured to project a plurality of projected images into a projection field. Each projected image is characterized as a distinct perspective view of the scene. The holographic diffuser is configured to display the plurality of projected images projected by the single projector. The mirror arrangement is fixedly positioned in the projection field. The mirror arrangement is configured to reflect the plurality of projected images onto the holographic diffuser from distinct directions. The directions are such that a 3D image is perceived by a person viewing the holographic diffuser.
