Abstract

A method for collinear non-interferometric phase retrieval holographic data storage using a single reference pixel is proposed. The known embedded data of the signal beam in the traditional off-axis holographic data storage system is placed in the reference beam through the collinear holographic data storage system, which greatly improves the material utilization rate. And increasing the intensity of the reference beam can achieve phase retrieval using only one reference pixel. As the intensity of the reference beam becomes stronger within a certain range, the number of iterations gradually decreases. With this method, the phase retrieval can be achieved even when the total energy of the reference beam is less than the signal beam. In the simulation, the four-level phase pattern was recorded and the phase was restored correctly.
