Abstract:
An eye characteristic measuring apparatus comprising:a projecting optical system having a laser light source for projecting a measurement target to a fundus of an eye to be inspected by a bundle of rays emitted from said light source; a light receiving optical system for condensing the bundle of rays reflected from the fundus of the eye; a photoelectric detector for detecting light quantity distribution characteristics of an image formed by said light receiving optical system; and an arithmetic unit for calculating eye optical characteristic of the eye to be inspected based on a signal output from said photoelectric detector; wherein a deflecting optical member for deflecting the bundle of rays being incident into both optical paths of said projecting optical system and said light receiving optical system is arranged so as to be rotatable, and thereby, a speckle noise is averaged for an imaged formed on the photoelectric detector.
