Abstract
Techniques are described for designing and manufacturing a refractive surface that produces a desired image when placed over a target image. The refractive lens surface may include a set of lens patches, each of which indexes a region on the source image to refract light from the indexed region to recreate a patch of the target image. And together, the lenses reproduce the target image. In one embodiment, the refractive geometry of the lens surface (i.e., the shape of each lens) is determined by formulating and efficiently determining a solution to an inverse light transport problem. The solution may account for additional constraints imposed by the physical manufacturing procedure. Doing so results in a design for a refractive surface amenable to milling (or other manufacturing process).
