Patent ID: 7216980

Claim:
An eye characteristic measuring apparatus comprising: a first illuminating optical system including a first light source part for emitting a first light flux of a first wavelength, for illuminating a retina of a subject eye to be measured with the first light flux from the first light source part; a first light receiving optical system including a first light receiving part for forming a first received light signal as a first coordinate system from a received light flux, and a conversion member converting the light flux reflected and returned from the retina of the subject eye into plural beams and guiding them to the first light receiving part, wherein the conversion member and the pupil of the subject eye form a conjugated relation; a second light receiving optical system including a second light receiving part for forming a second received light signal, as a second coordinate system, including information of an anterior eye part from a received light flux, for guiding a second light flux including the information of the anterior eye part of the subject eye to the second light receiving part; a measurement part for obtaining a first optical characteristic of the subject eye on the basis of the first received light signal from the first light receiving part and a second optical characteristic of the subject eye on the basis of the second received light signal from the second light receiving part; a coordinate setting part for converting signals of the first and the second coordinate systems corresponding to a pupil of the subject eye included in the first and the second received light signals into signals of reference coordinate systems, respectively; and a conversion part for correlating, through the respective reference coordinate systems formed by the coordinate setting part, the first and the second optical characteristics of the subject eye obtained by the measurement part.
