Error analysis and compensation in the design of 3D holograms using spatial segmentation layer-based method

Abstract

The development of 3D holographic display technology represents a promising advancement in future display methods. A critical aspect of this technology involves compensating for the positional deviation of reconstructed images associated with each sub-hologram in the spatial segmentation layer-based method design of three-dimensional holograms. However, a significant issue that has been inadvertently overlooked in the design process is the alignment between the digital blazed grating and the hologram itself. This alignment is often constrained by initial parameters and other factors, resulting in approximate rounding errors during the design process. In this paper, we analyze and compare the influence of these parameters on alignment accuracy, establishing an error calculation model based on theoretical analysis. We further determine the acceptable error tolerance and propose a compensation scheme to address these discrepancies. The results show that both our error analysis theory and compensation method are effective and accurate, providing valuable guidance for the future design of three-dimensional holograms utilizing spatial segmentation layer-based methods.
