- Abstract
- Due to the lack of suitable phase distortion metrics, the optimization and evaluation of phase-holograms have relied on numerical reconstruction (NR) domain metrics. However, the necessity of NR for hologram processing leads to more intricate design and a higher computational burden. In this paper, we introduce a distribution-shifting (DS) algorithm to enable optimizing or measuring distortions directly in phase-domain, considering 2π-periodicity and shift-invariance. Experimental results with various noise types demonstrate a strong correlation between phase-domain metric with DS and their NR-domain counterparts. We believe that our DS-metric could facilitate direct optimization approaches in various phase-hologram processing techniques. © 2024 IEEE.
