Single-shot detection method for intensity-phase-modulated multilevel signals using the designed phase mask
Year: 2025
Type: article
Abstract: We propose what we believe to be a newly designed phase mask for holographic storage systems (HDS) and performed detection and evaluation of intensity-phase modulated multilevel signals. By adding phase signals to the non-signal regions where signals were not assigned in the conventional designed phase mask, we doubled the transfer rate and increased the recording density by approximately 1.1 times while maintaining the effect of crosstalk noise suppression.
