Eye characteristic measuring apparatus

摘要

The invention provides an apparatus which detects light quantity distribution characteristics of a measuring target image projected to a fundus of an eye to be inspected and measures eye optical characteristics from the light quantity distribution characteristics. A projecting optical system has a light source and projects a measurement target to a fundus of an eye to be inspected by bundle of rays emitted from the light source, and a light receiving optical system condenses the bundle of rays reflected from the fundus of the eye. A photoelectric detector detects light quantity distribution characteristics of an image formed by the light receiving optical system, and an arithmetic unit measures eye optical characteristics of the eye based on a signal output from the photoelectric detector. A deflecting optical member for deflecting bundle of rays incident into both optical paths of the projecting optical system and the light receiving optical system is arranged so as to rotatable.
