Ophthalmologic imaging apparatus

摘要

Provided is an ophthalmologic imaging apparatus required by the position adjustment of a fixation lamp to be turned on, by a simple operation which includes: a scanning unit; an irradiation unit for irradiating an eye to be inspected with a measuring beam through the scanning unit; a fixation lamp; a lighting position changing unit for changing a lighting position of the fixation lamp; an optical path length difference changing unit for changing an optical path length difference between the measuring beam and a reference beam corresponding to the measuring beam based on the lighting position of the fixation lamp which is changed by the lighting position changing unit; and an acquisition unit for acquiring a tomographic image of the eye to be inspected based on a beam obtained by superimposing, on the reference beam, a return beam from the eye to be inspected, which is irradiated with the measuring beam.

主权项

1. An ophthalmologic imaging apparatus, comprising:
an irradiation unit configured to irradiate an eye to be inspected with a measuring beam; a fixation lamp; a lighting position changing unit configured to change a lighting position of the fixation lamp; an optical path length difference changing unit configured to change an optical path length difference between the measuring beam and a reference beam corresponding to the measuring beam; a control unit configured to control, when the lighting position of the fixation lamp is changed by the lighting position changing unit, the optical path length difference changing unit to change the optical path length difference with a changing amount corresponding to a changing amount of the lighting position of the fixation lamp; and an acquisition unit configured to acquire a tomographic image of the eye to be inspected based on a beam obtained by combining the reference beam with a return beam from the eye to be inspected, which is irradiated with the measuring beam.
