Multipass scanner for near-eye display

A near-eye display for providing an image in angular domain at an eyebox, the near-eye display comprising:

• a plurality of light sources for providing a plurality of light beams;
• a tiltable reflector for reflecting the plurality of light beams at a variable angle;
• a pupil-replicating waveguide comprising a polarization-selective in-coupler for in-coupling light in a first polarization state while transmitting through light in a second, orthogonal polarization state;
• a plurality of adjacent curved reflectors for receiving the plurality of light beams from the plurality of light sources and reflecting the plurality of light beams in the second polarization state through the polarization-selective in-coupler to impinge onto the tiltable reflector at different angles;
• wherein upon reflection from the tiltable reflector, the plurality of light beams are in the first polarization state, whereby the plurality of light beams are in-coupled into the pupil-replicating waveguide.

A method for coupling light beams into a waveguide of a near-eye display, the waveguide comprising a polarization-selective in-coupler configured to in-couple light in a first polarization state while transmitting through light in a second polarization state orthogonal to the first polarization state,

• the method comprising:
• collimating the light beams by a plurality of curved reflectors to provide collimated light beams;
• redirecting the collimated light beams in the second polarization state through the polarization-selective in-coupler to impinge onto a common tiltable reflector;
• reflecting, by the tiltable reflector, the collimated light beams at a variable angle to impinge onto the polarization-selective in-coupler;
• and
• in-coupling, by the polarization-selective in-coupler, the collimated light beams, wherein the collimated light beams are in the first polarization state after reflecting from the tiltable reflector.
