Abstract:
Systems and methods for incoupling light into a waveguide. A system includes a transfer optic and an optical scanner being configured to receive light from an optical engine. The optical scanner includes a first scan mirror positioned close to the transfer optic. The system further includes a waveguide with an incoupler positioned close to the transfer optic, which is configured to direct the light from the optical engine to the first scan mirror and to transmit light reflected from the first scan mirror to one of a second scan mirror or the incoupler of the waveguide.
