However, the bottleneck problem of insufficient 3D resolution seriously affects the experience of the viewer. The prior art solution uses a composite pinhole array and a composite image element array to solve the above problems. However, the prior art solutions have the following problems:
(1) And reconstructing a one-dimensional 3D image by each one-dimensional image element through the one-dimensional pinhole corresponding to the one-dimensional image element. However, a portion of the light rays emitted by two-dimensional image elements adjacent to the one-dimensional image element also pass through the one-dimensional pinhole and interfere with the one-dimensional 3D image reconstructed by the one-dimensional image element.
(2) Each two-dimensional image element reconstructs a two-dimensional 3D image through the two-dimensional pinholes corresponding to the two-dimensional image element. However, a portion of the light rays emitted by one-dimensional image elements adjacent to the two-dimensional image element also pass through the two-dimensional pinhole and interfere with the two-dimensional 3D image reconstructed by the two-dimensional image element.
(3) The optical efficiency is still low.
