An apparatus and a method for optimized calculation of 2D sub-holograms for object points of a three-dimensional scene and a pipeline for real-time calculation of holograms are provided. The invention shortens the calculation time of a hologram for representing a three-dimensional scene and/or to reduce the calculation complexity of such a hologram. This is achieved by a 2D sub-hologram of an object point, which has image elements of the spatial light modulator, comprises a half 1D sub-hologram, where the radius of each image element is determined and each image element of the 2D sub-hologram is fixedly assigned to at least one image element of the half 1D sub-hologram with identical or similar radius by way of an electronic circuit, by a method for encoding a hologram, and by a pipeline on the basis of FPGA and/or ASIC.
A pipeline for real-time calculation of holograms comprising a calculator to calculate sub-holograms and a controller to control a holographic display, the calculator and the controller are each configured as functional units, where the pipeline is realized on the basis of at least one application field programmable logic gate array and/or at least one application-specific integrated circuit, where the functional units are configurable during the runtime.
