While precise phase modulation hardware is becoming available, phase retrieval algorithms are still in their infancy, and holographic display ap- proaches resort 

We built a holographic display-camera setup (left) to generate data that is used to train a neural Because of its simple optical system setup and robust noise tolerance, non-interferometric phase retrieval is an important technique for phase-modulated holographic data storage. Usually, the iterative algorithm of non-interferometry needs hundreds of iteration numbers to retrieve phase accurately, the data transfer rate decreases severely. In digital holographic interferometry, phase difference can be determined by digital phase subtraction between the initial and second states, and fringe pattern evaluation is not required. In digital holography, spatial frequency is limited by the electronic devices [ 1 , 2 ]. Low-Photon Holographic Phase Retrieval David A.
