Abstract

【課題】分散補償を効果的に行うことが可能な眼底観察装置を提供する。 【解決手段】眼底観察装置１は、広帯域光（低コヒーレンス光Ｌ０）を信号光ＬＳと参照光ＬＲとに分割し、眼底Ｅｆを経由した信号光ＬＳと参照ミラー１７４を経由した参照光ＬＲとを重畳させて干渉光ＬＣを生成し、干渉光ＬＣの検出結果に基づいて眼底Ｅｆの画像を形成する光画像計測装置として機能する。眼底観察装置１は、眼球情報２１２ａに基づいて参照光ＬＲの分散の影響を補正し、その補正後に低コヒーレンス光Ｌ０に基づく干渉光ＬＣを生成し、この干渉光ＬＣを検出し、その検出結果に基づいて眼底ＥｆのＯＣＴ画像を形成する。それにより、眼球光学系による分散の影響を考慮した効果的な分散補償を行うことが可能となる。
