Abstract
Methods and systems for measuring optical aberrations of an eye are provided. In one embodiment, the present invention provides transmitting light from the eye along an optical path to an aberration sensor. An adaptive optic is disposed along the optical path between a target optical system and the aberration sensor. Aberrations of the adaptive optic can be adjusted in response to a signal generated by the aberration sensor so as to provide a desired sensed aberration. The shape of the adjusted adaptive optic can be determined with the aberration sensor by transmitting an adaptive optic configuration measurement beam along the optical path.
