米国出願第14/555,585号(2014年11月27日出願)、米国出願第14/690,401号(2015年4月18日出願)、米国出願第14/212,961号(2014年3月14日出願)、および米国出願第14/331,218号(2014年7月14日出願)。
(分野)
本開示は、拡張現実結像および可視化システムを含む光学デバイスに関する。
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、またがるはそのように知覚され得る様式でユーザに提示される。仮想現実または「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シナリオは、実世界内のオブジェクトによってブロックされているように見えるAR画像コンテンツ、または別様に実世界内のオブジェクトと相互作用するように知覚されるAR画像コンテンツを含み得る。
本願は、可変屈折力を提供するために採用され得るシステムおよび方法の議論を含む。可変焦点または可変屈折力デバイスは、画像が異なる深度から生じているかのように画像を投影する、ある頭部搭載型ディスプレイデバイスにおける用途を見出し得る。頭部搭載型ディスプレイデバイス内の光学要素の屈折力を変化させることによって、頭部搭載型ディスプレイデバイスの装着者に提示される画像は、装着者から異なる距離に位置するかのように見える。可変焦点または可変屈折力光学デバイスは、したがって、画像コンテンツがユーザに対して異なる場所に据え付けられているかのように、異なる画像コンテンツを表示させるために変調されることができる。いくつかの可変屈折力要素は、可動膜から成る反射体を備えている。他の可変屈折力要素は、切り替え可能な液晶要素を使用して屈折力レベル間で切り替わり得る液晶切り替え可能なデバイスを備えている。本明細書に説明されるいくつかの可変焦点デバイスは、光の偏光特性を利用して、1つの焦点から別の焦点への切り替えを促進する。
画像を形成するための光を出力するように構成された光学ディスプレイと、
ディスプレイからの光を受け取るように配置された1つ以上の導波管と、
フレームであって、フレームは、導波管を眼の前方に配置するように構成され、1つ以上の導波管は、前方側および後方側を有し、後方側は、前方側より眼に近い、フレームと、1つ以上の導波管の前方側に配置された可変屈折力反射体であって、可変屈折力反射体は、電気信号の印加に応じて調節可能な屈折力を有するように構成されている、可変屈折力反射体と、

ウェアラブル拡張現実頭部搭載型ディスプレイシステムは、頭部搭載型システムを装着している装着者の前方の世界からの光を装着者の眼の中に通すように構成されることができる。頭部搭載型ディスプレイシステムは、画像を形成するための光を出力するように構成された光学ディスプレイを含むことができる。ディスプレイシステムは、フレームを含み得、フレームは、眼の前方にある導波管を含み、1つ以上の導波管は、前方側および後方側を有し、後方側は、前方側より眼に近い。システムは、ディスプレイからの光を受け取るように配置された1つ以上の導波管を含み得る。可変屈折力反射体が、1つ以上の導波管の前方側に配置されることができる。反射体は、電気信号の印加に応じて調節可能な屈折力を有するように構成されることができる。システムは、1つ以上の導波管からの光を抽出するために1つ以上の導波管に対して配置された1つ以上の外部結合要素をさらに含み得る。要素は、導波管内で伝搬する光の少なくとも一部を可変屈折力反射体に導き得る。可変屈折力反射体から導かれた光は、導波管を通り眼の中に反射され、ディスプレイからの画像を装着者の眼の中に提示し得る。
図10Aに図示されるように、ウェアラブル拡張現実頭部搭載型ディスプレイシステム60は、例えば、導波管2700を介して、光プロジェクタシステム2000からの光を受け取るように配置された可変屈折力反射体(または可変焦点反射体)1032を含み得る。可変屈折力反射体1032は、電気信号の印加に応じて調節可能な屈折力を有するように構成され得る。例えば、図10Aに示される可変屈折力反射体1032は、調節可能な形状を有する変形可能反射表面(例えば、導波管2700に最も近い表面)を有する変形可能反射体を備えている。例えば、変形可能反射体1032の形状は、異なる屈折力に対応する異なる凸形状を生成するように曲がるように構成され得る。可変屈折力反射体1032は、例えば、可撓であり、その形状を変動させ得る変形可能膜または他の薄い部材を備え得る。いくつかの設計では、変形可能反射体1032は、電気的に作動させられる。変形可能反射体は、ある場合、静電力を介して、またはある他のものによって反射表面を変形させるための電場を印加するために、例えば、少なくとも1つの電極1036を含み得る。図10Aに図示されるように、別の電極1042が、導波管2700の表面上に含まれる。2つの電極1036および1042を横断した電圧の印加は、そのような電場を提供し得、したがって、変形可能反射体を変形させ得る。変形可能膜または部材の変形に伴って、反射表面(例えば、導波管2700に最も近い表面)は、変形させられ得る。図示されるように、形状は、凸面であり、したがって、負の屈折力を有する反射表面を提供することができる。いくつかの例では、導波管2700に最も近い表面は、光投影システム(ディスプレイ)2000からの光を反射するための反射表面を備え得るが、可変屈折力反射体に関連付けられた他の表面も、光投影システムからの光を反射し得る。可変屈折力反射体1032は、例えば、光導波路2700に最も近い表面である必要はない1つ以上の反射表面を含む複数の層を含み得る。可変屈折力反射体1032は、ある波長および/または偏光状態を有する光が可変屈折力反射体1032によって反射される一方、他の波長および/または偏光状態を有する光が可変屈折力反射体1032を通して透過させられるように、波長選択的および/または偏光選択的であり得る。
