Abstract
A system for displaying a virtual image to a user includes a light engine to generate a display light representing the virtual image, a diffractive waveguide, and an incoupler and outcoupler that are each optically coupled to the diffractive waveguide. In operation, the incoupler receives the display light from the light engine and directs the received display light to the diffractive waveguide, and the outcoupler directs at least a portion of the display light from the diffractive waveguide to an eye of the user. The diffractive waveguide is configured to converge a first component light of the generated display light at a first focal distance from the eye of the user, and to converge one or more additional component lights of the generated display light at one or more distinct other focal distances from the eye of the user.
