Patent ID: 7222962

Claim:
An ophthalmic measuring apparatus, comprising: a first illumination optical system including a first light source to emit a light flux of a first wavelength, and for illuminating to be condensed on a vicinity of a retina of a subject eye with a first illumination light flux from the first light source; a first light receiving optical system including a first conversion member to convert a reflected light flux reflected from the retina of the subject eye into at least 17 beams and a first light receiving part to receive the plural light fluxes converted by the first conversion member as first and second signals, and the first light receiving optical system is for guiding the reflected light flux to the first light receiving part by lenses; first movement means for moving a light condensing position of the first illumination optical system; second movement means for optically moving the first light receiving part and the first conversion member; an adjustment part configured to adjust positions of the first illumination optical system and the first light receiving optical system by the first and the second movement means to measure the first and second signals under plural measurement conditions until a measurement of an optical characteristic of the subject eye is enabled by combining at least the first and second signals from the first light receiving part; and an arithmetic part configured to obtain the optical characteristic of the subject eye by combining the first and second signals obtained from the first light receiving part under the plural measurement conditions in a process of adjustment of the adjustment part, wherein, the arithmetic part is configured to obtain a density of point images or an interval of point images or a point image level from the first signals of the first light receiving part, and judge whether there is a region in which the density of point images or the interval of point images or the point image level is outside the predetermined range, in case where there is such a region, the adjustment part controls the first and the second movement means so that the density of point images or the interval of point images or the point image level of the region falls within the predetermined range and, the arithmetic part is configured to input the second signals from the first light receiving part, combine the first and second signals, and obtain the optical characteristic of the subject eye based on the combined signals.
