ABSTRACT:
A radiant energy interlace system comprises an electromagnetic radiant energy reflector means having a magnetic core which includes a reed mirror portion and a body portion. The reed mirror portion is either a polished plate or frame of magnetic material holding a mirror and the body portion is of magnetic material having a center section with a centrally disposed ridge from which downwardly sloping surfaces extend to solid bar reel sections surrounded by coils of conductive wire. End sections of magnetic material having sloping surfaces for continuing the sloping surface of the center section complete the body section. A circuit is connected to the coils for alternately energizing the coils to magnetize alternate portions of the reed mirror portion to rotate the reed mirror portion about the fulcrum ridge of the center section. The slope of the body portion surfaces is equal to one half of the desired interlace angle.
