Description
本発明は、アメリカ国立科学財団により与えられた許可番号第dmr−0423914号及び国防高等研究計画局(DARPA)により与えられた許可番号第PO10023237号の政府の支援によりなされたものである。合衆国政府は、本発明に対して特定の権利を有する。
図2は、本発明の非球面GRINレンズを構築するために用いられる変形可能なポリマー材料からなるGRINシートのための一つの例示的な構成を示すグラフである。この実施例では、一連のナノ積層されたエラストマーTHV/EOポリマー膜は、ガラス状のPMMA/SAN−17系と同様のGRIN分布を形成するように生産及び積層された。特に、THV/EO積層ポリマーGRINシートは、約1.37から約1.48の範囲の屈折率で生産された。屈折率の変化は、各膜内の体積によるEOのパーセンテージにより変化された。
