Abstract

We propose a system for designing and manufacturing transparent/refractive surfaces such that when light passes through them the focusing/bending of light produces a desired image (caustic). Our surfaces are arrays of micro-lenses. Each micro-lens focuses light to a anisotropic Gaussian footprint at some specified projection plane. Given a budget of NxN micro-lenses, we approximate a desired image as a superposition of anisotropic Gaussians. We then perform an optimization process to assign each Gaussian footprints to a micro-lens such that the resulting surface meets certain constraints imposed by the manufacturing process
