Designing a Freeform Optic for Oblique Illumination

Abstract

Abstract:The Functional Freeform Fitting (F 4 ) method is utilized to design a freeform optic for oblique illumination of Mark Rothko's Green on Blue (1956). Shown are preliminary results from an iterative freeform design process; from problem definition and specification development to surface fit, ray tracing results, and optimization. This method is applicable to both point and extended sources of various geometries.
