Abstract
An ophthalmologic imaging apparatus includes a housing configured to include an optical system that irradiates a subject's eye with measurement light and receives returning light returned from the subject's eye irradiated with the measurement light, a rotation unit configured to rotate the housing by making a predetermined position on an optical axis of the optical system as a rotation center, a position changing unit configured to change a position of the rotation center on the optical axis of the optical system, and a holding unit configured to hold a positional relationship between the housing and the subject's eye when the position of the rotation center on the optical axis of the optical system is changed.

An ophthalmologic imaging apparatus comprising:
- a housing configured to include an optical system that irradiates a subject's eye with measurement light and receives returning light returned from the subject's eye irradiated with the measurement light;
- a rotation unit configured to rotate the housing by making a predetermined position on an optical axis of the optical system as a rotation center;
- a position changing unit configured to change a position of the rotation center on the optical axis of the optical system;
- and
- a holding unit configured to hold a positional relationship between the housing and the subject's eye when the position of the rotation center on the optical axis of the optical system is changed.
