Holographic metamaterial negative film and preparation system and method of holographic metamaterial optical device

The invention relates to the technical field of holographic metamaterial optical devices and preparation and control of the holographic metamaterial optical devices, and provides a holographic metamaterial negative film and a preparation system and method of the holographic metamaterial optical devices. The orientation layer is arranged on one side of the substrate; the liquid crystal layer is arranged on the side, away from the substrate, of the orientation layer, the liquid crystal layer comprises a plurality of liquid crystal molecules, and the liquid crystal molecules close to the orientation layer are arranged in the normal direction of the liquid crystal molecule layer where the liquid crystal molecules are located or are arranged in the mode of deviating from the normal direction of the liquid crystal molecule layer where the liquid crystal molecules are located by regulating and controlling the chiral strength of the liquid crystal layer. By controlling the intensity of chirality, a plurality of liqui
