| A hologram is constructed from individual subholograms assigned to corresponding encoding regions in a light modulation device and respectively assigned to an object point of the object to be reconstructed with the hologram. With a virtual observer window, a defined viewing region is provided through which a reconstructed scene in a reconstruction space is observed by an observer. A complex value of a wavefront for each individual object point is calculated in the virtual observer window. Each individual amplitude of a complex value of a wavefront in the virtual observer window is subsequently multiplied by a correction value with which a correction of the angle selectivity of at least one volume grating arranged downstream in the beam path of the light modulation device is carried out. The corrected complex values determined in this way for all object points are summed and transformed into the hologram plane of the light modulation device. | ||||||
