1. 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 including a polarizer, a switchable polarization rotator and a polarization-sensitive reflector,
wherein the polarizer is configured to receive the image light from the light projection system and to only output image light with a first polarization state,
wherein the switchable polarization rotator is configured to receive the image light with the first polarization state and to selectively change a polarization state of the received image light to a second polarization state,
wherein the polarization-sensitive reflector is configured to receive the image light from the switchable polarization rotator and to reflect image light having the first polarization state and transmit image light having the second polarization state, and
wherein the optical router is configured to provide, at different times, the left-eye image light to the left eyepiece and the right-eye image light to the right eyepiece.
