本開示は、ディスプレイシステムに関し、より具体的には、光の多重化に関する。
現代のコンピューティングおよびディスプレイ技術は、いわゆる「仮想現実」または「拡張現実」体験のためのシステムの開発を促進しており、デジタル的に再現された画像またはその一部が、現実であるように見える様式、またはそのように知覚され得る様式でユーザに提示される。仮想現実、すなわち、「VR」シナリオは、典型的には、他の実際の実世界の視覚的入力に対する透過性を伴わずに、デジタルまたは仮想画像情報の提示を伴い、拡張現実または「AR」シナリオは、典型的には、ユーザの周囲の実際の世界の可視化に対する拡張としてのデジタルまたは仮想画像情報の提示を伴う。複合現実または「MR」シナリオは、一種のARシナリオであり、典型的には、自然世界の中に統合され、それに応答する仮想オブジェクトを伴う。例えば、MRシナリオでは、AR画像コンテンツは、実世界内のオブジェクトによってブロックされて見え、または別様にそれと相互作用するように知覚され得る。
