Paper Abstract

We recently completed a preliminary design of a novel illumination system. The concept of this design is to integrate the incident irradiance from a small source such that an otherwise non-uniformly iluminated target is uniformly illuminated, while maintaining high radiometric throughput. Our design incorporates a collector to efficiently gather flux from the source, two multi-element faceted arrays, and a flux relay. We explore the concept behind our design and show a preferred embodiment and its predicted peformance.
