Claim One:
1. Method for holographically reconstructing a scene, comprising: dividing the scene 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, computing a computer-generated hologram (CGH) of each object point group and encoding on a light modulator means which is illuminated by coherent light that is emitted by a light source means, generating a reconstruction from each CGH of an object point group and superposing the generated reconstructions incoherently by adding up individual CGHs, so that a single holographic reconstruction of the scene becomes visible in a plane of an eye position of an observer, and providing the system controller means 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 a 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 lateral distances between the object points of that group which are characterising of visible resolution and the complex values of the object points.
