Abstract
Devices, systems and methods including an optic having an optical surface partitioned into a plurality of facets. Wherein a geometry of the plurality of facets are configured to rearrange the rays in an incident light field to form a desired irradiance pattern on a projection surface, partitioned into a plurality of pixels, each of which may receive light from a multiplicity of facets. Wherein the configured geometry of the plurality of facets is corrected to minimize a difference between an observed irradiance pattern and a desired irradiance pattern provided by a user.
