Abstract
Abstract: :
Purpose: To develop a high-resolution adaptive optics system with the goal of providing high-accuracy correction of the wave aberrations of the eye for vision science investigations, psychophysics and retinal imaging. Methods: We have built an adaptive optics system based on a Liquid Crystal Spatial Light Modulator wavefront correction device with over 200,000 (480 x 480) phase control points. The system also utilizes a Hartmann-Shack wavefront sensor with up to approximately 300 subapertures in the pupil (20 across an 8 mm pupil). Results: This adaptive optics system is capable of diffraction-limited correction of the wave aberrations of the eye for pupil sizes up to 8 mm. Conclusion: The high-quality wave aberration correction achievable with this system should enable quantitative studies of the limits of human spatial contrast sensitivity and resolution, and changes associated with aging and retinal disease.
