Near-eye display with frame rendering based on reflected wavefront analysis for eye characterization

摘要

A near-eye display system includes an array of lenslets overlying a display panel. The display panel includes an array of light projecting elements, each light projecting element being coaxial with an axis of a corresponding lenslet. The display panel further includes an array of light detecting elements and an array of sub-pixel elements. The system further includes a control component configured to activate the array of light projecting elements to project a pattern of light spots toward an eye of the user and to control the array of light detecting elements to capture an image representing a reflection of the projected pattern of light spots from the eye. The system also includes an analysis component to determine displacements between expected positions and actual positions of at least a subset of light spots in the captured image, and to characterize the eye based on the displacements.
