Abstract
A near-eye optical assembly includes a display waveguide and an optical structure. The display waveguide is configured to receive display light and to direct the display light to an eye of a user. The optical structure includes an input coupler, an optical path, and an output coupler. The input coupler is disposed to receive a portion of the display light that propagates through the waveguide. The optical path directs the portion of the display light from the input coupler to an output coupler that is configured to provide the received portion of the display light to a disparity sense circuit.
