摘要: A crossover network is obtained by using a plurality of similar optical stages. Each stage includes two light paths that combine at an output plane. One path provides the direct connection while other connection. To realize this capability, each comprises beam splitter element accepts containing image array and develops therefrom beams are directed in different paths. Along one path, means provided for reversal selected segments sending reversed or crossed-over through combiner. second applying to combiner without reversal. disclosed prismatic mirror. The number corners such mirror differs from stage.
