Abstract:
1. An ophthalmologic apparatus comprising: a first light source configured to emit a first measuring beam; a second light source configured to emit a second measuring beam; a first limitation unit disposed in an optical path connecting the first light source with a subject's eye and configured to limit entry of the first measuring beam into the subject's eye; a second limitation unit disposed in an optical path connecting the second light source with the subject's eye and configured to limit entry of the second measuring beam into the subject's eye; an aberration measurement unit configured to measure aberration caused by a subject's eye by using a return beam of the first measuring beam from the subject's eye; a correction unit configured to correct aberration of the return beam of the second measuring beam from the subject's eye caused by the subject's eye based on the aberration measured by the aberration measurement unit; a first acquisition unit configured to obtain a first image of the subject's eye by using the aberration-corrected return beam of the second measuring beam from the subject's eye; and a control unit configured to allow, in lit states of the first light source and the second light source, one of the first measuring beam and the second measuring beam to enter into the subject's eye while limiting entry of the other measuring beam into the subject's eye by controlling the first limitation unit and the second limitation unit.
