Abstract
We report on two methods of designing the input signal images for controlling or exploiting crosstalk
noise in holographic data storage systems. The first is a phase detection method using crosstalk noise.
By placing phase-known pixels in the signal patterns, the signal phase can be extracted by a single image
acquisition without requiring multi-step interferometric measurements. The other method suppresses
and controls crosstalk noise in intensity-modulated multivalued signals. By appropriately designing the
signal patterns, the intensity modulation owing to the interference with noise diffracted light can be significantly
reduced. The signal detection error rates in these methods were evaluated using our holographic
simulator, and the effectiveness of our proposed methods was discussed in terms of recording
density.
