ABSTRACT

Non-imaging optics is well suited to transfer light from an emitter to a receiver. In many applications, efficient light transfer is not sufficient, and a given irradiance pattern is also desired. Shaping the output wavefronts of a non-imaging optic provides extra degrees of freedom that allow the light output to be shaped. By shaping the output wavefronts, non-imaging optics may be designed to generate a prescribed irradiance pattern on a receiver, or a prescribed intensity pattern on the far field. There are two main groups of design problems in non-imaging optics. The first group is called “bundle-coupling” and its goal is to maximize the light power transferred between emitter and receiver. The second group is called “prescribed irradiance” or “prescribed intensity” and its goal is to produce a desired irradiance pattern on a receiver.
