Abstract
【解決手段】波長「λ」の光線のためのカスタム位相板は基本の屈折率「n0」を有するプラスチックの板材を含む。この板材の表面には異なる屈折率を有する隣接した複数のスポットが形成されている。そして、このスポットは、光線から光学収差を除去する回折パターンを確立する。具体的には、各スポットは、kλ/10(ここでk=1〜10)に等しい、基本の屈折率(n0)に対する選択された光路差(OPD)を有する。更に、パターン内の各スポットについてのOPDは、プラスチック材料を超短パルスのレーザ光で加熱することによって個別に確立される。

Claims (3)
- 波長「λ」を有する光線から、光学収差を除去するためのカスタム位相板であって、
前記カスタム位相板は、
表面を有する透明な板材と、
回折パターンを確立するために前記板材の前記表面に形成された複数の隣接するスポットとを備え、
前記板材の基本の屈折率は「n0」であり、
各スポットは、前記基本の屈折率「n0」に対して選択された光路差「OPD」を有し、OPD=kΔn=kλ/10であり、ここでk=1〜10であり、
前記回折パターンは、前記カスタム位相板を通過する前記光線が実質的に収差のない収束をつくるために、所定の光学収差を前記光線から除去するようになっているカスタム位相板。 - 各スポットの屈折率の変化「Δn」は、前記スポットをレーザ光で加熱することによりつくられた請求項1に記載されたカスタム位相板。
- 前記カスタム位相板が、前記表面に形成された局所的な屈折領域を更に備え、
前記局所的な屈折領域は、付加的に屈折率を変化させることを特徴とし、前記回折パターンに付加される請求項1に記載されたカスタム位相板。
