PROBLEM TO BE SOLVED: To provide an optical interference tomographic device capable of reducing a scanning time and suppressing the cost of a device.SOLUTION: An ophthalmologic device includes: scanning means for scanning an eye to be examined with a measuring beam first acquisition means for acquiring a tomographic image for observation of the eye to be examined based on the interference light in which the return light of the measuring beam from the eye to be examined scanned in a first scanning direction by the scanning means, and a reference beam corresponding to the measuring beam interfere with each other second acquisition means for acquiring a front image for observation of the eye to be examined based on a plurality of tomographic images acquired based on the interference light in which the return light of the measuring beam from the eye to be examined scanned in a second scanning direction by the scanning means, and a reference beam corresponding to the measuring beam interfere with each other, and control means for causing the second scanning direction to roughly coincide with the first scanning direction by controlling the scanning means.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2016,JPO&INPIT【課題】走査時間の短縮を図ることでき、更に、装置のコストを抑えた光干渉断層装置を提供する。【解決手段】測定光を被検眼に対して走査する走査手段と、前記走査手段によって第1の走査方向に走査された前記測定光の前記被検眼からの戻り光と前記測定光に対応する参照光とが干渉した干渉光に基づいて前記被検眼の観察用の断層像を取得する第1取得手段と、前記走査手段によって第2の走査方向に走査された前記測定光の前記被検眼からの戻り光と前記測定光に対応する参照光とが干渉した干渉光に基づいて得られた複数の断層像に基づいて前記被検眼の観察用の正面画像を取得する第2取得手段と、前記走査手段を制御することで前記第2の走査方向と前記第1の走査方向とを略一致させる制御手段とを備える。【選択図】図2
