| 摘要 |
The present invention suitably performs preparatory operations for optical coherence tomography of an eye to be tested. The ophthalmological imaging device according to an embodiment comprises a data acquisition unit and a control unit. The data acquisition unit repeatedly acquires data by repetitively scanning an eye being tested, using optical coherence tomography. The control unit performs a first control process for adjusting the optical path length difference between a sample arm and a reference arm in an interference optical system for optical coherence tomography so that an image of the eye being tested is positioned at a standard position in a frame, on the basis of the data repeatedly acquired by the data acquisition unit. The control unit further performs a second control process for changing the optical path length difference so that the image of the eye being tested is positioned at a new standard position in the frame, on the basis of the data repeatedly acquired by the data acquisition unit. |
