Holographic information processing method for time programming

The invention discloses a holographic information processing method for time programming. The holographic information processing method comprises the following steps: forming a two-dimensional perovskite thin film; measuring a hydration time constant of the two-dimensional perovskite thin film; designing a time programmable hologram; and according to the hydration time constant, the fs laser processing system is adopted to process the time programmable hologram on the two-dimensional perovskite thin film, so that the time dynamic control of the nano-scale single pixel is realized, and the crosstalk-free time multiplexing programmable hologram is realized through a reverse optimization algorithm. Wherein organic molecules of the two-dimensional perovskite thin film can be stripped from the material under fs laser irradiation, and layered perovskite can generate local structure and component change, so that the thickness of the material is reduced at nanoscale precision, and meanwhile, a sub-wavelength inorgani
