A holographic reconstruction system having spatial light modulators (SLM), an eye finder and a position control orients a propagating spatially modulated light wave field (LW) toward at least one eye position (EP3) of an observer's eye, thereby reconstructing a scene in a three-dimensional manner and tracking the same during a position change of the eye position. Through low mechanical and optical complexity, the invention enables unobstructed lateral and axial movement of the observer head to arbitrary eye positions in a tracking region. The use of additional, planar optical components, which bring about optical aberrations during a position change of observer eyes, are prevented. The reconstruction system according to the invention achieves the aim in that, in addition to the holographic scene information and data regarding the object position of associated object elements (OP1, OP2, OP3), a hologram processor means also takes the eye position data of the current eye positions into consideration in order, for one, to adjust the size and location of the hologram regions (H1, H2, H3) to the current eye position (EP3) and, secondly, to dynamically influence the encoding data for hologram regions such that, regardless of the current eye position, the system orients partial light waves modulated in a tracking region with the open light wave cones toward the current eye position.
