Abstract: Holography is a three-dimensional (3D) visualization technique that satisfies all the depth-cues and provides the most natural visualization. It is based on generation of an optical replica of the captured 3D object from the captured diffraction field. Holography is used in vast amount of application areas, such as in optical computing, optical metrology and microscopy, non-destructive testing and 3D imaging. Dynamic holographic reconstructions can be achieved by employing holographic video displays which may have pixelated structures. In practice, spatial light modulators (SLMs) are used in such purposes. The pixelated structure of SLMs can affect the quality of reconstructed objects. Hence, in order to obtain better reconstructions, pixelated structure of SLMs has to be taken into consideration. Rapid calculation of the diffraction field which is emitted by the object is just as important as the accuracy of the diffraction field.
