Description
(式1) Cos[2θ]・Sin[2α]
(式1) Cos[2θ]・Sin[2α]
において示される残余乱視の寄与に等しく且つ逆となるように、2つのゼルニケ多項式Z4およびZ5の結合から成る付加的な面を既存の面に加えることによって得られる。
(式1) Cos[2θ]・Sin[2α]
に等しく、部分6002においては、
(式2) Cos[2θ]・Sin[-2α]
に等しくなる。
上記の実施形態において、レンズは、実質的に等しい2つの部分に分割される。しかし、上で詳述したように、本発明はこの場合に限定されず、2つの部分は異なる寸法を有することができる。
上記のすべての実施形態において、補正の大きさは角度αに依存する。従って、αの各々の値に対して残余乱視を正確に矯正することは不可能である。しかし、レンズの可能な動きの範囲内でαの平均値を選択することができる。
