Abstract:
An ophthalmologic apparatus comprises a light source  12 , an optical measurement system  13  that radiates first light from the light source to inside an eye to be examined and guides first reflected light from the eye, an optical reference system ( 24, 22 ) that radiates second light from the light source to a reference surface and guides second reflected light from the reference surface, a photo detector  26  that detects interfering light between the first reflected light from the optical measurement system and the second reflected light from the optical reference system, and a processor that determines a position of a measuring portion of the inside of the eye based on the detected interfering light. The optical measurement system comprises an incident angle changing member  46  that changes an incident angle of the first light radiated to the eye within a predetermined angular range relative to an axis of vision of the eye.

Claim (Index 1):
An ophthalmologic apparatus comprising:\n a light source; an optical measurement system configured to radiate first light from the light source to inside an eye to be examined and guides first reflected light from the eye; an optical reference system configured to radiate second light from the light source to a reference surface and guides second reflected light from the reference surface; a photo detector configured to detect interfering light between the first reflected light from the optical measurement system and the second reflected light from the optical reference system; and a processor configured to determine a first position of a first measuring portion inside the eye based on the detected interfering light, wherein the optical measurement system comprises an incident angle changing member configured to change an incident angle of the first light radiated to the eye within a predetermined angular range relative to an axis of vision of the eye, the incident angle changing member is configured to scan the incident angle within the predetermined angular range during a measurement, the photo detector is configured to detect interfering light of each scan angle and output an interference signal of each scan angle to the processor, the interference signal of each scan angle includes a first signal component, the first signal component being created by the second reflected light and reflected light from the first position of the first measuring portion, and the processor is configured to determine the first position of the first measuring portion based on only the first signal component of the interference signal with respect to a first angular range with increased intensity of the interference signal which is higher than a first predetermined intensity.
