ABSTRACT:
A system for selectably concentrating and projecting electromagnetic radiation utilizes re-entrant reflecting surfaces and multiple internal reflections. The system of the present invention comprises components having a generally-shaped primary reflecting surface which may be used in conjunction with one or more generally-shaped secondary reflecting surfaces to achieve concentration of electromagnetic radiation along the direction of the projected beam for specified spatial radiation and collection patterns.
