Abstract
The present disclosure relates to a 3D integrated imaging device and a preparation method thereof. The 3D integrated imaging device includes a spacer layer, a three-dimensional structure layer, and a microlens array. The spacer layer has a preset thickness. The three-dimensional structure layer is disposed on a surface of a side of the spacer layer and includes a plurality of micro-nano structure units. The microlens array is arranged on a surface of a side of the spacer layer away from the three-dimensional structure layer and includes a plurality of microlenses. The plurality of micro-nano structure units correspond to the plurality of micro-lenses one by one. A front view pattern of the plurality of micro-nano structure units is a superposition of images formed by each layered image of a target stereoscopic image under the plurality of micro-lenses according to different depths of field after the target stereoscopic image is layered.
