A display system includes an optical device configured according to constructive interference for a plurality of wavelengths at a focal length. The display system includes a fiber. The display system includes a controller configured to scan the fiber using a Lissajous scanning method to generate a display. The display can be disposed within a focal plane of the optical device. The controller is configured to modulate light intensity from the fiber. The controller can be configured to form a display image that passes through the optical device. The display system can include an optical combiner configured to reflect the display image from the optical device and form a virtual image. The optical device can be configured to magnify a display image from the display and form a virtual image.

Meta-optics for virtual reality and augmented reality systems

An optical device includes a first zone including a first plurality of nanoscale elements. The first plurality of nanoscale elements has a first optical dispersion profile and a first orientation. The optical device has a second zone including a second plurality of nanoscale elements. The second plurality of nanoscale elements has a second optical dispersion profile and a second orientation. The first orientation and the second orientation are configured according to constructive interference for a plurality of wavelengths and a focal length.
