Abstract:
A method, apparatus, and system that provides a holographic layer as a micro-lens array and/or a color filter array in an imager. The method of writing the holographic layer results in overlapping areas in the hologram for corresponding adjacent pixels in the imager which increases collection of light at the pixels, thereby increasing quantum efficiency.
