One disclosed example provides a near-eye display device. The near-eye display device comprises an eye tracking system configured to determine a position of an eye of a user relative to the near-eye display device, and a waveguide including at least an input coupler and an output coupler, the output coupler including a plurality of zones, each zone activatable via a dynamically controllable output coupling element of the zone. The near-eye display device further comprises an image source configured to output image light to the input coupler, and a controller configured to selectively activate one or more zones of the output coupler based at least on the position of the eye.

Examples are disclosed that relate to using an array of hot mirrors in an eye-imaging system. One example provides a head-mounted display system, comprising a frame, an eye-imaging camera supported on the frame, a switchable hot mirror array comprising a plurality of switchable hot mirrors configured to direct light reflecting from an eye toward the eye-imaging camera, and a controller configured to control switching of a reflectivity of each of the plurality of switchable hot mirrors.
