Abstract (en)
Local adapted shapes on a reflector (1) are designed to give the reflector multiple focal points (10a,10b,110a,110b) separated by spaces. As a result, electromagnetic bundles (5a,5b,50a,50b) of rays emerging from rays (4a,4b,40a,40b) separated by spaces are directed at a common illuminating area (3a,3b), especially for bundles with different frequencies/bands that illuminate the reflector. <??>An Independent claim is also included for a method for determining the shaping of a reflector's surface.
Abstract (de)
Die Erfindung betrifft einen Reflektor mit geformter Oberfläche für elektromagnetische Wellen, wobei eine lokale Formgebung des Reflektors (1) derart ausgelegt wird, daß der Reflektor (1) mehrere, räumlich getrennte Foki (10a, 10b, 110a, 110b) aufweist. Es können dadurch von räumlich getrennten Strahlern (4a, 4b, 40a, 40b) ausgehende elektromagnetische Strahlbündel (5a, 5b, 50a, 50b), insbesondere solche verschiedener Frequenz oder Frequenzbänder, die den Reflektor (1) ausleuchten, auf ein gemeinsames Ausleuchtgebiet (3, 3a, 3b) gerichtet werden. <IMAGE>
