Title:
眼光学特性測定装置
Document Type and Number:
Japanese Patent JP4630126
Kind Code:
B2
Abstract:
An eye's optical characteristics measuring system, comprising a first target projection optical system for projecting a target image on a fundus of an eye under test, a first photodetecting means for receiving the target image reflected from the fundus of the eye under test from the first target image projecting optical system, an ocular refractive power measuring unit for measuring ocular refractive power of the eye under test based on photodetection result from the first photodetecting means, a second target projecting means for projecting a spot-like target image to the fundus of the eye under test, a second photodetecting means for receiving the target image reflected from the fundus of the eye under test, and an eye's optical characteristics measuring unit for measuring ocular refractive power based on two or more images acquired at a predetermined refractive degree pitch before and after centering the refractive degree of the eye under test obtained by the second photodetecting means.
