Apparatus and method for operating a real time large diopter range sequential wavefront sensor
First Claim
1. A wavefront sensor comprising:
- a light source configured to illuminate a subject eye;
a detector to output wavefront information;
an image sensor configured to output an image of the subject eye;
a computer, coupled to the light source, the image sensor, and the detector, with the computer configured to analyze the image or wavefront information to detect a presence of an unintended object in a wavefront relay path or a moving away of the subject eye from a desired position or range that reduce confidence in wavefront measurements of the subject eye.

Abstract
A wavefront sensor includes a light source configured to illuminate a subject eye, a detector, a first beam deflecting element configured to intercept a wavefront beam returned from a subject eye when the subject eye is illuminated by the light source and configured to direct a portion of the wavefront from the subject eye through an aperture toward the detector and a controller, coupled to the light source and the beam deflecting element, configured to control the beam deflecting element to deflect and project different portions of an annular ring portion of the wavefront from the subject eye through the aperture and further configured to pulse the light source at a firing rate to sample selected portions of the annular ring at the detector.
