Abstract

被測定物体の注目部位の高精度の画像を迅速に取得できる光画像計測装置を提供する。眼底観察装置１は、低コヒーレンス光Ｌ０を信号光ＬＳと参照光ＬＲ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を重畳させて干渉光ＬＣを生成して検出し、その検出結果を基に眼底ＥｆのＯＣＴ画像を形成する光画像計測装置である。眼底観察装置１は、眼底Ｅｆに対して信号光ＬＳを走査する走査ユニット１４１と、信号光ＬＳの一連の走査を行うときに、走査ユニット１４１を制御して走査間隔を変更させつつ信号光ＬＳを走査させる制御部２１０とを備えている。それにより、注目部位については小さな走査間隔で高精度の画像を取得でき、他の部位については大きな走査間隔で走査時間を短縮できる。したがって、眼底Ｅｆの注目部位の高精度の画像を迅速に取得できる。
