- 測定光束を発する光源と、被検眼瞳と略共役位置に配置された第1の絞りを有し被検眼眼底に向けて測定光束を投影する為の投影系と、被検眼瞳と略共役位置に配置した第2の絞りを有し該第2の絞りを介し被検眼眼底から反射された測定光束を光電検出器上に投影する受光系とを有し、前記光電検出器上での光量分布特性から被検眼の眼光学特性を測定する眼光学特性測定装置に於いて、前記第1の絞りと第2の絞りとを光軸上に位置し、同開口径の絞りに設定する為の第1の設定条件と、前記第1の絞り及び第2の絞りの一方だけを所定の微小開口径を有する基準小開口絞りに設定する為の第2の設定条件とを選択し得る様に構成すると共に、前記第1の設定条件での前記光電検出器上での光量分布特性から被検眼眼球光学系の周波数伝達関数を算出し、前記第2の設定条件での前記光電検出器上での光量分布特性から被検眼眼球光学系の位相伝達関数を算出し、前記周波数伝達関数及び前記位相伝達関数に基づいて被検眼眼底に形成される視標像をシミュレーション画像として演算することを特徴とする眼光学特性測定装置。
- 前記設定条件の内の開口径の1つは測定光束を被検眼瞳孔より小さな所定径に制限し、前記設定条件の内のもう1つの開口径は測定光束を被検眼光軸近傍に限定する様制限する請求項1の眼光学特性測定装置。
- 前記第1の絞り、第2の絞りの少なくとも一方は、測定光束を被検眼瞳孔より小さな所定径に制限する少なくとも1つの絞り孔と、測定光束を被検眼光軸近傍に限定する様制限する少なくとも1つの絞り孔とを有する絞り板である請求項1の眼光学特性測定装置。
- 前記第1の絞り、第2の絞りの少なくとも一方は、測定光束を被検眼瞳孔より小さな所定径に制限する少なくとも1つの絞り孔と、測定光束を被検眼光軸近傍に限定する様制限する少なくとも1つの絞り孔とに切替可能な電子絞り装置である請求項1の眼光学特性測定装置。
