Fig. 7 provides a movable splicing mode, and by separating the substrate 71 and fixing and adjusting the substrate through an external mechanical device, an independent splicing submodule is formed, so that the system can be controlled more flexibly. Because the design of the nanometer phase structure is independent for a single projection system, each splicing submodule has certain independence relatively, the matching of each single projection device 110 and the corresponding splicing submodule 121 is ensured, and finally, the reconstruction of a three-dimensional light field can be realized in an observation area through the joint adjustment of all parts, so that a better three-dimensional stereo display effect is achieved.
