“…In domestic, Han Chao etc. put forward a method that the phase-only object function can be obtained by calculating repeatedly when the amplitude of object function and the amplitude of its Fourier transformation are known, and then generated the binary holographic by the binary coding of cosine [6], the amount of computational data is large and this method is limited in computer generated hologram.

Since the resolution of digital micro-mirror device (DMD) which is used to reconstruct the digital holograms captured in experiments is relatively low, only a part of the digital hologram can be effectively reproduced in the experiment. For the hologram has the feature of high redundancy, in this paper, we propose that compress holograms based on Binary holographic interference. First, only the amplitude of the digital hologram is retained after Fresnel diffraction, recover the phase information from the amplitude, then generate a new compressed digital hologram with the phase and amplitude, and then process the new hologram according to the principle of binary holographic interference to improve the diffraction efficiency and to obtain a high-quality reconstruction.
