In the computing of the hogels, the field superposition is conducted in the spectrum domain by using the elemental tables. Because the signal energy always concentrates in a small spectrum region, these regions are cropped as the elemental tables. Subsequently, the fields are Fourier transformed to the spectrum domain. In SDLUT, diffraction fields on the hogel plane of selected reference points in the object space are calculated. Here, we proposed a fast calculation scheme of DA-CGHS by the spectrum-domain look-up table (SDLUT) method. However, its computing cost is extremely high because numerous scenes together with depth information must be calculated. High-definition depth-added computer-generated holographic stereogram (DA-CGHS) is superior in its high quality, easy realization, and auto-shading effect. Thus, a strategy for efficient intensity accumulation is suggested. Finally, there is an upper-quality limit of the reconstructed image by intensity accumulation. In addition, if the computational efficiency is a concern, the CGH calculated with iterations is not recommended for intensity accumulation display. Using this model, we have confirmed that the randomness induced by random phase is equivalent to that induced by random down-sampling for the generation of binary CGHs. In this paper, we propose an empirical formula of the average noise based on the speckle phenomenon in a laser projector. However, there is no simple method to predict the dependence of the average noise and accumulation number, and we can only know the results after finishing the full computation. Intuitively, the quality of the reconstructed image should be proportional to the number of intensity accumulation. If enough randomness is added to the CGHs, the speckle noise can be mostly averaged out. Thanks to the fast frame rate of the binary spatial light modulator, the speckle can be significantly suppressed by intensity accumulation, i.e., the sequential display of multiple CGHs of the same scene. Reuse of the collection (replication, reprinting and printout) is strictly prohibited.The image generated by binary computer-generated holograms (CGHs) always suffers from serious speckle noise.
