Abstract
A direct retinal projector system that provides dynamic focusing for virtual reality (VR) and/or augmented reality (AR) is described. A direct retinal projector system scans images, pixel by pixel, directly onto the subject's retinas. This allows individual pixels to be optically affected dynamically as the images are scanned to the subject's retinas. Dynamic focusing components and techniques are described that may be used in a direct retinal projector system to dynamically and correctly focus each pixel in VR images as the images are being scanned to a subject's eyes. This allows objects, surfaces, etc. that are intended to appear at different distances in a scene to be projected to the subject's eyes at the correct depths.
