ABSTRACT:
Radiant energy emitted from a source (e.g., a door of, or a workpiece within, an industrial furnace), which would otherwise be lost, is recuperated by the placement of an array of reflective cells in the path of the emitted beam. Each reflective cell comprises multiple reflecting surfaces for reflecting the incident beam back toward the opening even if the beam is not perpendicular to any of the reflecting surfaces. The individual facets of each cell are shaped to reduce scattering losses. Additionally, secondary arrays of reflective cells can be employed to intercept, and thus recuperate, even the reduced amount of rays scattered from the primary array. Focusing techniques are employed to minimize dispersion losses.
