Projector integrated with a scanning mirror

A waveguide display system, comprising:

• a waveguide having a first surface and a second surface, the waveguide including an incoupling DOE (diffractive optical element) and an outcoupling DOE;
• a point light source disposed adjacent to the first surface of the waveguide, wherein the point light source is configured to provide a divergent input light beam to a portion of the waveguide outside the incoupling DOE;
• a scanning mirror disposed adjacent to the second surface of the waveguide, the scanning mirror configured to receive the divergent input light beam from the point light source through the waveguide and to provide a divergent reflected light beam toward the incoupling DOE of the waveguide;
• a collimating scanning optical element positioned adjacent to the first surface of the waveguide, the collimating scanning optical element being configured to receive the divergent reflected light beam emitted from the scanning mirror through the incoupling DOE of the waveguide and to produce a collimated reflected light beam toward the incoupling DOE of the waveguide;
• wherein the incoupling DOE is configured to:
• prevent the divergent reflected light beam from the scanning mirror from propagating to the outcoupling DOE in the waveguide through total internal reflection (TIR);
• and
• cause the collimated reflected light beam to propagate to the outcoupling DOE in the waveguide through total internal reflection (TIR).

A waveguide display system, comprising:

• a waveguide having a first surface and a second surface, the waveguide including an incoupling DOE (diffractive optical element) and an outcoupling DOE;
• a cantilever scanner disposed adjacent to the first surface of the waveguide, the cantilever scanner is configured to provide a scanning light beam;
• a reflective optical element disposed adjacent to the cantilever scanner and configured to receive the scanning light beam and to provide a reflected scanning light beam;
• a collimating optical element disposed adjacent to the reflective optical element and configured to receive the reflected scanning light beam from the reflective optical element and to provide a collimated scanning light beam;
• and
• a scanning optical element disposed adjacent to the collimating optical element and configured to receive the collimated scanning light beam and to provide a collimated two-dimensional scanning light beam;
• wherein the cantilever scanner, the reflective optical element, the collimating optical element, and the scanning optical element are disposed on a same side of the waveguide, adjacent to the first surface;
• wherein the waveguide is configured to receive the collimated two-dimensional scanning light beam at the incoupling DOE and to propagate the collimated two-dimensional scanning light beam to the outcoupling DOE through total internal reflection (TIR).
