EYE REFRACTIVE POWER MEASUREMENT APPARATUS |
摘要 |
An eye refractive power measurement apparatus includes: a measuring optical system for projecting measurement light onto a fundus of an examinee's eye, and causing a two-dimensional imaging device to capture the measurement light to be reflected from the fundus as a plurality of target pattern images at different distances from a measurement optical axis; a light deflecting member arranged at a position out of a conjugate position with a pupil of the examinee's eye on an optical path of the measuring optical system; a rotor for rotating the light deflecting member about an optical axis of the measuring optical system to allow a plurality of pattern light beams to be eccentrically rotated on the pupil; and a calculator for measuring an eye refractive power of the examinee's eye based on a target pattern image to be captured by the two-dimensional imaging device. |
