Abstract

Embodiments of the invention generally provide apparatuses and methods utilized in optics, and more specifically to apparatuses and methods for adaptive optics correction and imaging. Real-time wavefront sensorless adaptive optics correction and imaging is used with the living human eye to produce optical quality rivaling that of wavefront sensor based control in the similar systems. Using an optimization algorithm that is based on an image quality metric, the apparatus and method optimize the optical quality in ocular image frames acquired with an adaptive optics system.

First claim

What is claimed is:

1. A method of performing adaptive optics correction of an eye, the method comprising the steps of:
a. causing light to enter the eye;
b. receiving a first image of the light emitted or reflected from the eye;
c. computing a first image quality metric value for at least a portion of the first received image;
d. using an optimization algorithm that is based on an image quality metric to adjust a first correcting element to increase the computed image quali…
