Abstract
In various embodiments, an optical system to present an image to an eye of a user is disclosed. The system comprises a waveguide configured to output collimated light towards an optically powered element comprising at least one holographic component to generate optical power. The optically powered element is configured to receive the output collimated light from the waveguide and direct the received light towards the eye of the user and impart an angular offset on the directed light such that the directed light forms a virtual image plane.

An optical system to present an image to an eye of a user, the optical system comprising:
- a waveguide configured to output collimated light towards an optically powered element, the optically powered element comprising a holographic layer with a fixed optical power,
- the optically powered element is configured to receive the outputted collimated light from the waveguide and an optical power of the optically powered element is changed by the holographic layer changing a phase of the received collimated light and adjusting a curvature of the optically powered element, and the optically powered element directs the light having the changed phase towards the eye of the user with an angular offset from the received collimated light, the directed light forming a virtual image plane.
