Restoration of a blurred retinal image with liquid-crystal adaptive optics based on feedback interferometry

A novel imaging system with liquid-crystal adaptive optics-based on feedback interferometry is described for high-resolution retinal imaging. The performance of the system was verified by experiments using an artificial eye consisting of a lens, an aberration plate, and a resolution test target. We observed that an image of the test target (mimicking a retina) blurred by the aberration plate (mimicking ocular aberrations) was successfully restored immediately after our. adaptive optics system was activated.
