Method and apparatus for fixation measurement and refraction error measurement using wave-front error

摘要

A method and apparatus for fixation measurement includes projecting, by an image projector, a stimulus onto one or more eyes of a patient via a beam splitter, and capturing, by one or more image sensing devices disposed conjugate to the one or more eyes, a reflected image including light reflected from the one or more eyes in response to the stimulus, the reflected image including information indicating the fixation of the one or more eyes.
