摘要： A system and method for concentrating the intensity of light emitted by a high-intensity source for delivery to a remote target, so that the power density of the active radiating region of the source is nearly restored at the target. The source is surrounded by a plurality of nonimaging concentrators. If the source is elongated, the concentrators are similarly elongated and parallel to the source. If the source is compact, the preferred geometric pattern of the concentrators is dodecahedral. The geometry of the concentrators is designed in accordance with the edge-ray principle of nonimaging optics. Channels such as optical fibers or light pipes are coupled optically to the absorbers of the concentrators, to conduct the concentrated light to the remote target.

摘要： Ultra-compact concentrators and illuminators that approach the thermodynamic limit to optical performance can be realized with purely imaging strategies. Two-stage reflector systems where each optical surface is tailored to eliminate one order of aberration—so-called aplantic designs are described. The contours are monotonic functions that can be expressed analytically—important in facilitating optimization studies and practical fabrication. The radiative performance of the devices presented herein is competitive with, and even superior to, that of high-flux nonimaging systems. Sample results of practical value in solar concentration and light collimation are presented for systems that cover a wide range of numerical aperture.
