摘要
An apparatus comprising a diffractive combiner having a front side, a back side, and a combiner optical axis running substantially through the diffractive combiner and normal to the back side. A display unit having a display optical axis that directs the display light along the display optical axis toward the diffractive combiner. An eye-tracking sensor having a sensor optical axis that is positioned to receive eye-tracking radiation reflected by the diffractive combiner along the sensor optical axis. The combiner optical axis, the display optical axis, and the sensor optical axis intersect each other at the diffractive combiner.
