Paper Abstract

A point-focus solar concentrator is described for use in high temperature terrestrial and space applications. The system comprises a nonimaging reflective lens in the form of a ring array concentrator coupled to a fiber optic bundle through which the concentrated light is transmitted. Unlike mirror-based systems, the concentrator is a ring array composed of concentrically nested elements focusing energy to the rear of the structure. Energy is transported from the concentrator by optical fibers and directed at a target where high heat flux is needed. The fiber optic bundle is tailored for solar energy transmission and includes a fused end to minimize inter-fiber losses at the injection point. The integrated system is intended to produce concentrated thermal energy without the need for electricity intensive heating elements. Optical efficiency is investigated through a ray trace analysis.
