Abstract

We report on a single-shot phase detection method for holographic data storage systems using polychromatic reconstruction (PCR). In PCR, the multi-step interferometric measurements cannot be applied for signal phase detection, because the reconstructed image consists of the broad spectral components spatially distributed within the page. Our proposed method utilizes inter-pixel crosstalk caused by an aperture inserted in the Fourier plane of the input image, and does not require any interferometric measurements, like a four-step phase-shifting method. We have numerically investigated pixel error rates of phase-encoded signals in PCR, and confirm the validity of our proposed method.
