    Abstract

    The wavefront modulation system, which swiftly and flexibly performed the wavefront measuring and shaping in a coherent time, is vital in biomedical and optical communications. This high-speed wavefront modulation system, in particular, sets the basis for the effective application of coherent beams in the rapidly-changing scattering media, and digital micromirror devices combined with computed holography are an efficient method for the implementation of this technology. In this study, first, the importance, research advancement, and the application of high-speed wavefront modulation at coherent optical areas were introduced; thereafter, various binary computed holographic methods used in the current wavefront modulation technique were reviewed. The principles and the features of the holographic methods were specifically discussed, existing challenges in the holographic algorithm were summarized, and the trend of the binary computed holography was forecasted.
