Abstract
An ophthalmologic apparatus includes an acquisition unit and a controller. The acquisition unit includes an optical scanner capable of deflecting light in a predetermined deflection angle range. The acquisition unit is configured to acquire data of a subject's eye by performing A-scan on the subject's eye using optical coherence tomography by measurement light deflected by the optical scanner. The controller is configured to cause the acquisition unit to perform A-scan based on a deflection operation state of the optical scanner.
Claims16
An ophthalmologic apparatus, comprising
- an acquisition unit including an optical scanner capable of deflecting light in a predetermined deflection angle range and configured to acquire data of a subject's eye by performing A-scan on the subject's eye using optical coherence tomography by measurement light deflected by the optical scanner;
- and
- a controller configured to cause the acquisition unit to perform A-scan based on a deflection operation state of the optical scanner,
- wherein the controller is configured to cause the acquisition unit to perform A-scan so that intervals between projection positions of the measurement light on the subject's eye are substantially equal.
An ophthalmologic apparatus, comprising:
- an acquisition unit including an optical scanner capable of deflecting light in a predetermined deflection angle range and configured to acquire data of a subject's eye by performing A-scan on the subject's eye using optical coherence tomography by measurement light deflected by the optical scanner;
- and
- a controller configured to cause the acquisition unit to perform A-scan based on a deflection operation state of the optical scanner,
- wherein the controller is configured to cause the acquisition unit to perform A-scan so that intervals between the deflection angles are substantially equal.
A method of controlling an ophthalmologic apparatus including an optical scanner capable of deflecting light in a predetermined deflection angle range, the method comprising:
- an acquisition step of acquiring data of a subject's eye by performing A-scan on the subject's eye using optical coherence tomography by measurement light deflected by the optical scanner;
