Claim:
1. An eye-tracked head-mounted display, comprising: a micro-display for generating an image to be viewed by a user, the micro-display having a display optical path and an exit pupil associated therewith; a first plane located at the micro-display and a second plane located at the exit pupil; an image sensor configured to receive reflected optical radiation from the second plane reflected from a user's eye positioned thereat, the image sensor having a sensor optical path associated therewith; and display optics disposed in optical communication with the micro-display along the display optical path and in optical communication with the image sensor along the sensor optical path, the display optics having a selected surface closest to the micro-display and the image sensor, the display optics located relative to the micro-display and image sensor such that the display and image sensor optical paths impinge upon differing respective portions of the selected surface, wherein the display optical path and sensor optical path each comprise respective optical axes at the display optics and image sensor, respectively, and wherein the optical axes are tilted relative to one another at the second plane.
