Claim One:
1. Method for holographically reconstructing a scene, where the scene is divided by parallel section layers into object points by software means, where the object points are selected in accordance with a defined grid in the section layers and combined to form object point groups by system controller means, where a computer-generated hologram (CGH) is computed of each object point group and encoded on a light modulator means which is illuminated by coherent light that is emitted by a light source means, where a reconstruction means generates a reconstruction from each CGH of an object point group and superposes the generated reconstructions incoherently by adding up the individual CGHs, so that a single holographic reconstruction of the scene becomes visible in the plane of the eye position of an observer, and where the system controller means are provided with storage means for storing data records of the object points, wherein the system controller means perform both the selection of object points in the section layers according to the grid and the combination of object points to form object point groups in dependence on the visible resolution of the reconstruction of the scene, where the system controller means Generate the section layers at different distances from the eye position and define in each section layer a grid in which the object points are situated so close to each other that their mutual distance is smaller than the visible resolution of the reconstruction of the scene for that section layer, and Combine those object points of the respective section layer whose mutual distance is larger than the visible resolution of the reconstruction of the scene to form an object point group, and compute the CGH of the object point group from the data records which comprise the lateral distances between the object points of that group which are characterising of the visible resolution and the complex values of the object points.
