Claim 16:
17. A head-mounted display system comprising:
a head-mountable frame;
a light projection system comprising an emissive micro-display, wherein the light projection system is configured to output image light comprising left-eye image light for forming left-eye images time-multiplexed with right-eye image light for forming right-eye images;
a left eyepiece supported by the frame;
a right eyepiece supported by the frame; and
an optical router configured to:
receive the image light from the light projection system, and
provide, at different times, the left-eye image light to the left eyepiece and the right-eye image light to the right eyepiece,

wherein the left eyepiece comprises one or more left-eye waveguides, each left-eye waveguide comprising:
a left-eye polarization-sensitive in-coupling optical element configured to in-couple light having the first polarization state into the left-eye waveguide; and
a left-eye out-coupling optical element configured to out-couple in-coupled light out of the left-eye waveguide,

wherein the right eyepiece comprises one or more right-eye waveguides, each right-eye waveguide comprising:
a right-eye polarization-sensitive in-coupling optical element configured to in-couple light having the second polarization state into the right-eye waveguide; and
a right-eye out-coupling optical element configured to out-couple in-coupled light out of the right-eye waveguide, and

wherein the left-eye polarization-sensitive in-coupling optical element and the right-eye polarization-sensitive in-coupling optical element are disposed in a same image light path.
