1results about How to "Polarization insensitive" patented technology

The application discloses an image sensor based on a super-structured surface color routing. The image sensor comprises an upper super-structured surface layer and a lower pixel layer, wherein the pixel layer is composed of a plurality of pixel units arranged in cycles, each pixel unit comprises four pixels, namely R, G, B and N pixels; the super-structured surface is composed of super-structured units, and the cycle of the super-structured units is consistent with the cycle of the pixel units; the super-structured surface is used for separating incident light in the visible to near-infrared range into four colors and focusing the four colors on the four pixels respectively. The application can route incident light in the 400-1100 nanometer wave band to four image sensor pixels arranged in a 2*2 array, correspond to blue, green, red and near-infrared channels respectively, and directly realize color imaging.
