Abstract
An image display system can include a plurality of light sources configured to emit uncollimated light, and an eyepiece waveguide having an input port configured to receive beams of light at differing angles. The image display system also includes a scanning mirror having a surface with positive optical power configured to receive light emitted by the plurality of light sources. The surface with positive optical power is configured to collimate light emitted by the plurality of light sources to form a plurality of collimated light beams and direct the plurality of collimated light beams to the input port.
