Abstract

Light field, or plenoptic, imaging involves gathering the intensity and incoming angle of light at each pixel, which can enable image refocusing, changing the point of view, or reconstructing the depth map. Current light field imaging techniques, such as micro-lens arrays or stacked transmission gratings lead to bulky and sophisticated systems with limited angular sensing range and resolution. Here we introduce a fast metasurface-based angle sensitive pixel design procedure using the discrete dipole approximation. Compared with traditional FDTD-based design procedures, we can find optimal designs in approximately an order of magnitude less time.
