Abstract

Phase-modulated holographic data storage shows a great prospect in Ultra-high-definition (UHD) information display and data storage due to its higher capacity than amplitude modulation. However, the phase reconstruction is more sensitive to noise in the spectrum plane. In this paper, we proposed to use the low-depth camera to obtain the spectral intensity of the reconstructed beam, and used iterative Fourier transform algorithm to retrieve phase. Simulation and experiment show that this method has stronger noise suppression performance.
