Metastructure surface element and image processing device

Abstract

The utility model discloses a metasurface element and an image processing device, the metasurface element comprises a substrate, a first microstructure array and a second microstructure array, the first microstructure array is arranged on the substrate and is used for three-dimensional imaging; and the second microstructure array is arranged on one side, deviating from the first microstructure array, of the substrate and is used for enhancing image edge signals. When the super-structure surface element is used in the image processing process, the intensity and angle information of the target is obtained through one-time shooting, and then three-dimensional imaging and edge detection of the target can be conveniently and rapidly achieved. 本实用新型公开了一种超构表面元件以及图像处理装置，其中，所述超构表面元件包括基底、第一微结构阵列和第二微结构阵列，所述第一微结构阵列设置于所述基底上，用于三维成像；所述第二微结构阵列设置于所述基底上背离所述第一微结构阵列的一侧，用于加强图像边缘信号。本申请的超构表面元件在图像处理过程中使用时，通过一次拍摄获取目标的强度和角度信息，进而可方便快速地实现对目标的三维成像及边缘检测。
